A garrison is provided with ration for 60 soldiers to last for 72 days. Find out how many days they will last if soldiers are 40 and they increase their intake by 20%?
It is a case of indirect proportion
More men, Less days
Number of days = (60 × 72)/(40 × 120/100) = 90 days
In the following question, select the related number from the given alternatives.
54 : 135 ∷ 32 : ?
The logic followed here is:
54 : 135 → (27 × 2 = 54; 27 × 5 = 135)
32 : ? → (16 × 2 = 32; 16 × 5 = 80)
Hence, the answer is ‘80’.
The compound interest on a certain sum for 2 years is Rs. 41 and the simple interest is Rs. 40. Find the rate % p.a.

The number of males per hundred females in a country was 120. At the next census, the total population increased by 5% and the female population increased by 10%. Find the increase percent in the male population.
Given, the number of males per hundred females in a country was 120.
Let the number of females be 100a, thus the number of males will be 120a.
Given, at the next census, the total population increased by 5% and the female population increased by 10%.
Let the % increase in the population be ‘b%’
∴ b% of 120a + 10% of 100a = 5% of 220a
⇒ 1.2b + 10 = 11
⇒ b = 1/1.2 = 5/6% = 0.8333%
Direction: In the question below are given three statements followed by three conclusions numbered I, II and III.

Three men, four women and six children can complete a work in seven days. A woman does double the work a man does and a child does half the work a man does. How many women alone can complete this work in 7 days?
Let 1 woman’s 1 day’s work = x
⇒ 1 man’s 1 day’s work = x/2 and 1 child’s 1 day’s work = x/4
⇒ (3x/2 + 4x + 6x/4) = 1/7
⇒ 28x/4 = 1/7
⇒ x = (1/7 × 4/28) = 1/49
⇒ 1 woman can complete the work in 49 days.
∴ To complete the work in 7 days, number of women required = (49/7) = 7

The students in three classes are in the ratio 4 : 6 : 9. If 12 students are increased in each class, the ratio changes to 7 : 9 : 12. Then the total number of students in the 2nd Class before the increase is
The Initial ratio is 4 : 6 : 9
Let the common ratio be ‘x’
Therefore the respective number of students in the 3 classes will be 4x , 6x and 9x
After addition of 12 students to each class,
The numbers will be 4x + 12 , 6x + 12, 9x + 12
The ratio after that will be 7 : 9 : 12
∴ (4x + 12)/(6x + 12) = 7/9
∴ 9 × (4x + 12) = 7 × (6x + 12)
∴ 36x + 108 = 42x + 84
∴ 6x = 24
∴ x = 4
∴ The initial number of students in the 2^{nd} class = 24

Which of the following is related to the Second Schedule of the Indian Constitution?
Directions: One statement is given, followed by two conclusions, I and II. You have to consider the statement to be true, even if it seems to be at variance from commonly known facts. You are to decide which of the given conclusions be definitely drawn from the given statement.
Statement: Admissions in all departments are closed since no more seats are vacant and students are actively involved in their academics.
Conclusions:
I. Students prefer to study any subject of their interest.
II. Importance of education is known to the students.
Answer: Option 4 is correct.
Solution: Since the seats in every department are filled without any vacancy it is known that the interest of every student varies and they tend to study various subjects. Also, the statement states that the students are involved in their academics very well, this shows the interest they have towards the subjects. Hence conclusion I follows, and II can also be concluded as it explains the reason for seats getting filled. We can determine that students really get to know the importance of education as the reason behind their involvement in academics is mentioned in the statement. It should be the importance and interest in education that drives the students towards their involvement.

There are three Kabaddi teams in a tournament A, B and C. If the difference between the average points of team A, B and B, C is 45, then what will be the difference of points between kabaddi team A and C?
As we know average = sum of all the observation/total number of observation
Average of (A, B) – Average of (B, C) = 45
⇒ (A + B)/2  (B + C)/2 = 45
⇒ A + B  B  C = 45 × 2
⇒ A  C = 90
∴ Difference between A and C = 90

A boy starts from his house and walks at a speed of 5 km/hr and reaches his school 3 minutes late. Next day he starts at the same time and increases his speed by 4 km/hr and reaches 3 minutes early. What is the distance (in km) between the school and his house?
Let the distance between the school and his house be ‘x’ km
Time taken on first day = Distance/speed = x/5 hrs.
His speed on next day = 5 + 4 = 9 km/hr.
Time taken on next day = x/9 hrs.
Now,
∵ He reached 3 min. late on the first day and reached 3 min. early the next day, this means that the difference between the time taken on the 2 days = 3 + 3 = 6 min. = 6/60 = 1/10 hrs.
⇒ x/5 – x/9 = 1/10
⇒ (9x – 5x)/45 = 1/10
⇒ 4x/45 = 1/10
⇒ x = 45/4 × 1/10
⇒ x = 1.125 km
∴ Distance between the school and his house is 1.125 km
Ram celebrated his birthday on 3rd April 2000 on Monday. Next time in which year will he will celebrate his birthday on the same date and day?
Number of odd days in 2000 = 1 (As 1^{st} April comes after February)
Number of odd days from 2000 till 2001 = 1 + 1 = 2
Number of odd days from 2000 till 2002 = 2 + 1 = 3
Number of odd days from 2000 till 2003 = 3 + 1 = 4
Number of odd days from 2000 till 2004 = 4 + 2 = 6
Number of odd days from 2000 till 2005 = 6 + 1 = 7 = 0 odd days
Hence, Ram’s birthday on 3^{rd} April 2006 will be on Monday.

A man is standing on a railway bridge, which is 70 m long. He finds that a train crosses the bridge in 5 and a half second, but crosses him in 2 seconds. Find the length of the train and its speed.
⇒ Let the length of the train be x metres
⇒ Then, the train covers x metres in 2 seconds and (x + 70) m in 11/2 seconds
⇒ (x + 70)/x = 5.5/2
⇒ x = 40
⇒ Speed = 40/2 m/sec = (20 × 18/5) km/hr = 72 km/hr
There are 52880 passengers who use Metro train. 49% of those use metro card and of those who use metro card are males. What percentage of passengers who use metro card are females?
Let the total passengers who use metro train be 100
So, number of passengers who use metro card = 100 × 49/100 = 49
now, = 1/7
So, number of male passengers who use metro card are males= 49 × 1/7 = 7
So, number of passengers who use metro card are females= 49  7 = 42
So, percentage of passengers who use metro card are females = 42.

The total population of a city is 57000. Out of this 85 % are literate. 45% of the total population are women. Out of the total literate population, men and women are in the ratio of 11 : 8 respectively.
Q. What is the total number of literate men and illiterate women?
Total population of a city is 57000. Out of these 85% are literate.
∴ literate population = 57000 × 0.85 = 48450
⇒ Illiterate population = 57000 – 48450 = 8550
Out of the total literate population, men and women are in the ratio of 11 : 8 respectively.
∴ Literate women = 8/19 × 48450 = 20400
⇒ Illiterate women = 25650 – 20400 = 5250
⇒ literate men = 48450 – 20400 = 28050
Required number = 28050 + 5250 = 33300

⇒ x = 1200
∴ Marked price of the watch = Rs. 1200
By Selling 5 articles for 18rupee, a man losses 10%. If he sells 3 articles for Rs. 15, then what will be the profit percentage?
Let, cost price of 5 article = Rs. x
Price at 10% loss = Rs. 18
According to problem,
⇒ x  x × 10/100 = 18
⇒ 0.9x = 18
⇒ x = 20
∴ Cost price of 5 article = Rs. 20
∴ Cost price of 3 article = Rs. 20 × 3/5 = Rs. 12
Selling price of 3 article = Rs. 15
∴ Profit percentage,
⇒15−1212×100%⇒15−1212×100%
⇒ 25%

On a TV channel four serials P, M, C and G were screened, one on each day, on four consecutive days but not necessarily in that order. On which day was serial C screened?
I. The first serial was screened on 23rd, Tuesday and was followed by serial G.
II. Serial P was not screened on 25th and one serial was screened between serials P and M.
Given, four serials P, M, C and G were screened, one on each day, on four consecutive days.
From statement 1: The first serial was screened on 23^{rd}, Tuesday and was followed by serial G.
We cannot conclude day of serial C.
From statement 2: Serial P was not screened on 25^{th} and one serial was screened between serials P and M.
We can’t judge anything about C from it because nothing else is known as starting day or information about G or C or serial P and M are screened before 25^{th} or after it etc.
On combining 1 and 2:
From 1 and 2 clearly P and M fits only on 23^{rd} and 25^{th} date resp. and only 26^{th} date is left for C Hence serial C is screened on 26^{th} date on Friday.
Thus both the statements are required to answer the question.

Buccal cavity:
The ratio of weekly incomes of A and B is 9 : 7 and the ratio of their expenditures is 4 : 3. If each saves Rs. 200 per week, then the sum of their weekly incomes is
Given ratio of weekly income of A and B is 9 : 7 and ratio of their expenditure is 4 : 3.
Let the weekly income of A is Rs. 9x and weekly income of B be Rs. 7x
We know that, Expenditure = Income – Savings
Since savings of both A and B is Rs. 200. Thus,
Weekly expenditure of A = (9x – 200)
Similarly, weekly expenditure of B = (7x – 200)
Since the ratio of weekly expenditure is 4 : 3, hence
⇒ 27x – 600 = 28x – 800
⇒ x = 200
Hence, the weekly income of A = 9 × x
= Rs. 1800
Also, weekly income of B = 7 × x
= Rs. 1400
∴ The sum of weekly income of A and B = Rs. (1800 + 1400)
= Rs. 3200

The numbers 3446, 5887 and 2445 are put side by side in the same order making a 100 digits number. Find the remainder when this 100 digit number is divided by 9.
Since the number is of 100 digits and 3446, 5887 and 2445 are put side by side in the same order;
∴ 3446 must be repeated 9 times, 5887 & 2445 must be repeated 8 times;
∴ Sum of digits of 100 digits number = [3 + 4 + 4 + 6] × 9 + [5 + 8 + 8 + 7 + 2 + 4 + 4 + 5] × 8
⇒ 153 + 344
⇒ 497
Reminder when 497 is divided by 9 = 2
Hence, the remainder when the 100 digit number is divided by 9 would be 2.
Given, √5 = 2.236
⇒ (√5 + 1)/(5  1)

What is the sum of all natural numbers between 100 and 400 which are divisible by 13?
The first and last number between 100 and 400 which are divisible by 13 are 104 and 390 respectively.
The numbers will be in arithmetic proportion because the common difference is 13, so the first term is 104 and the last term is 390.
So, T_{n} = a + (n – 1) × d
⇒ 390 = 104 + (n – 1) × 13
⇒ n = 23
⇒ S_{n} = n/2 × (a + l) = 23/2 × (104 + 390)
⇒ S_{n} = 5681
∴ The sum of all natural numbers between 100 and 400 which are divisible by 13 is 5681

Directions: A statement is given followed by two inferences I and II. You have to consider the statement to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given inferences, if any, follow from the given statement.
Statement: During Sheila Dikshit's tenure from 1998 to 2013, Delhi got an infrastructure boost with the metro chugging through the most congested neighborhoods, public transport switching to CNG and new flyovers adding to road space.
Inferences:
I: Before the construction of the metro, commuting through tight roads was very tough.
II: Before 1998, Delhi's infrastructure was not up to the mark.
Metro has chugged though the tight neighbourhoods. So obviously it was hard to commute though them before metro. Also, the government must have spent a lot of money on this. Government won’t spend money on something which is already up to the mark. So the infrastructure must have been poor before 1998. Hence both the inferences follow.

Directions: The question below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give an answer.
Among P, Q, R, S, and T sitting in a straight line, facing North, who sits exactly in the middle of the line?
I. P sits third to the left of S. T is an immediate neighbor of P as well as R.
II. T sits second to the left of S. Q is not an immediate neighbor of either T or S.
From statement I:
Hence the following 2 cases arise (North is up for all diagrams):
Case I:
Clearly we cannot determine exactly who is in the middle.
From statement II:
Again the following four cases arise:
Case I & II:
Again we cannot determine whether S or T comes in the middle.
From the statement, I & II combined:
Only the following case satisfies all the conditions.
Hence T occupies the middle position.
So the answer is ‘Data in both the Statement I and II together are necessary to answer the question.’

A dishonest shopkeeper cheats at time of buying and selling the products. He weights 20% more at time of buying and 10% less at time of selling. What is his total profit?
Given that he cheats 20% at time of buying
⇒ Goods bought = 1000(1 + 20/100)
⇒ 1200 g at price of 1000 g
Given that he cheats 10% at time of buying
⇒ Goods sold = 1000(1 – 10/100)
⇒ 900g at price of 1000 g
Since cost price = selling price
⇒ Profit percentage = goods left/goods sold × 100
⇒ [(1200 – 900)/900] × 100%
⇒ [300/900] × 100%
⇒ [1/3] × 100%
⇒ 33.33%
∴ Profit percentage = 33.33%
How does calcium carbide help in the ripening of mangoes?
In the figure, ABCD is a square. Find the length of tangent PC, if the radius of the circle is 5 cm.
Radius of the circle is 5 cm
∴ Side of the square AB = BC = 5√2 cm
Suppose PB = x cm
In ΔPBC
⇒ PC^{2} = [(5√2)^{2} + x^{2}]
We know that∶
PC^{2} = PB × PA
⇒ [(5√2)^{2} + x^{2}] = x × (x + 5√2)
⇒ 50 + x^{2} = x^{2} + 5√2x
⇒ x = 5√2 cm
∴ PC = √[(5√2)^{2} + x^{2}] = √(50 + 50) = 10 cm

We know that cyclicity of 7 is 4 only, so (7^{4 × 34}) will have the unit digit 1
⇒ Unit digit of (7^{139}) = Unit digit of (1 × 7^{3}) = Unit digit of 343
∴ Unit digit of (7^{139}) = 3
In case CO2 of earth’s atmosphere disappears, the temperature of the earth’s surface would
Carbon dioxide gas is crucial for the maintenance of lifesustaining temperature on Earth due to its property of trapping thermal solar radiation. The mechanism by which carbon dioxide traps heat in the atmosphere is commonly referred to as the "greenhouse effect", in absence of which Earth’s temperature would drop drastically.

Directions: The question below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give the answer.
Who amongst X, Z, B, D, and F was the first to reach the party hall?
I. Z, who reached earlier than F, X and B was not the first to reach.
II. X, who reached earlier than F and B could not reach earlier than D, who was at the party hall before Z.
Note: Here the person after ‘→’ is late one.
From statement 1: Z, who reached earlier than F, X and B was not the first to reach.
⇒ Z → F, X and B was not first to reach and only D is left,
so D reached the party first.
Hence, Data in statement I alone is sufficient to answer the question
From statement 2: X, who reached earlier than F and B could not reach earlier than D, who was at the party hall before Z.
⇒ X → F, B and D → X & D → Z
⇒ D → X → F, B & D → Z
Clearly, Data in statement II alone are sufficient to answer the question
from statements II we can depict that D is the first to reach the party hall.
Hence, Data in statement I alone or in statement II alone is sufficient to answer the question.

What is the positive value of m for which the roots of the equation 12x2 + mx + 5 = 0 are in the ratio 3 ∶ 2?
Let the roots be 3t and 2t respectively
Product of the roots = c/a
3t × 2t = 5/12
t^{2} = 5/72
∴ t = ± √5/(6√2)
Sum of roots = b/a
3t + 2t = m/12
60t = m
∴ m = 60 × ± √5/(6√2) = ± 5√10
Only positive value of m is required
∴ m = 5√10

If the roots of the equation x3 – 12x2 + 39x – 28 = 0 are in A.P., then their common difference will be;
Roots of Given equation x^{3} – 12x^{2} + 39x – 28 = 0 are in A.P.
Let α – β, α, α + β be the roots of the equation.
Here β is the common difference
Sum of the roots = α – β + α + α + β = b/a
3α = 12 ⇒ α = 4
and product =  d/a
(α – β) α(α + β) = 28
α = 4
(4 – β) 4(4+ β) = 28
(4 – β) (4+ β) = 28/4 = 7
16  β^{2} = 7
⇒ β = ± 3

Of the 5 subjects, the average marks of Rakesh in first 3 Subjects was 79 and the average marks in the last 3 subjects was 86. If his marks in the third subject were 80, then what were his average marks in all the 5 subjects?
We know,
Average = sum of all observations/number of observations
⇒ Average marks of Rakesh in first 3 subjects = 79
⇒ Sum of marks in first 3 subjects = 79 × 3 = 237
Also,
Average marks of Rakesh in last 3 subjects = 86
⇒ Sum of marks in last 3 subjects = 86 × 3 = 258
Marks in third subject = 80
Sum of marks in all the five subjects = 237 + 258  80 = 415
∴ Average of all the five subjects = 415/5 = 83
A man sells two articles. The cost price of the first article is equal to the selling price of the second article. The first article is sold at a profit of 20% and the second articles is sold at a loss of 20%. What is the ratio of the selling price of the first article and the cost price of the second article?
Let the cost price of the first article be Rs. ‘x’
But, the first article is sold at a profit of 20%,
⇒ Selling price of first article = x + 20% of x = x + x/5 = (6/5)x
Now,
Selling price of second article = Cost price of first article = Rs. x
But, the second article is sold at a loss of 20%,
⇒ (100  20)% of Cost price of second article = Selling price
⇒ 80% of Cost price of second article = Selling price
⇒ (4/5) × Cost price of second article = x
⇒ Cost price of second article = (5/4)x
∴ Required ratio = (6x/5) ∶ (5x/4) = 24 ∶ 25
