Three years ago, the average age of A and B was 8 years, With C joining them now, the average becomes 15 years. How old is C now?
Let the age of A be “x” years, B be ‘y’ years and C be “z” years.
Three years ago,
Age of A = x – 3 years
Age of B = y – 3 years
Average of age of A and B = (A + B)/2 = 8 years
⇒ (x + y 6)/2 = 8
⇒ x + y – 6 = 16
⇒ x + y = 22
Now average of A,B and C = 15 years
⇒ (A + B + C)/3 = 15
⇒ x + y + z = 45
⇒ 22 + z = 45
⇒ z = 23 years

Since the data about the age is not given.
The correct answer is Data inadequate.
What will be the average of all the prime numbers before 19?
Prime numbers before 19 = 17, 13, 11, 7, 5, 3, 2
We know, Average = sum of all the number/total number
∴ Average = (17 + 13 + 11 + 7 + 5 + 3 + 2)/7 = 58/7 = 8.28
5 men can do a piece of work in 12 days and 10 women can do the same work in 15 days. 5 men and 10 women undertook the same work for Rs. 36,000. They finished the work in 5 days with the help of 15 children. What is the share of 5 children?
Time taken by 5 men to do a piece of work = 12 days
∴ Work done by 5 men in 1 day = 1/12
Time taken by 10 women to do the same work = 15 days
∴ Work done by 10 women in 1 day = 1/15
With the help of 15 children they finished the work = 5 days
∴ Work done by (5 men + 10 women + 15 children) in 1 day = 1/5
So, work by 15 children in 1 day = 1/5  1/12  1/15 = 1/20
Time taken by 15 children to do the same work = 20 days
The ratio of their time = 12 : 15 : 20
We know, the efficiency is inversely proportional to the time
So, ratio of their efficiency = 1/12 : 1/15 : 1/20 = 5 : 4 : 3
So, 5 + 4 + 3 = 12 unit = 36,000
⇒ 1 unit = 3,000
⇒ 3 unit = 9,000
∴ Share of 15 children is 9,000
So, share of 1 child = 9,000/15 = 600
So, share of 5 children = 600 × 5 = 3,000

Thus the letters inside the triangle but not in the intersection of square and triangle represent Potters who are not Mothers i.e. IH.
Hence, the correct answer is IH.
M is the largest threedigit number which when divided by 6 and 5 leaves remainder 5 and 3 respectively. What will be the remainder when M is divided by 11?
Lcm of (6, 5) = 30
Let’s assume the number be "30K + constant", where Constant is the remainder.
let that number be ‘M’
⇒ M/6 = 5 (remainder)
M could be 5, 11, 17, 23, 29, ...
⇒ M/5 = 3 (remainder)
M could be 3, 8, 13, 18, 23, 28, ...
The very first number common in both term is 23.
⇒ M is 23 i.e. a constant term
⇒ 30K + constant = 30K + 23
The largest three digit number comes when K is 32
⇒ 30 (32) + 23 = 983
∴ When 983 is divided by 11, leaves the remainder 4.

Consider the horizontal relations,
In row 1, (7 × 5) – 2 = 35 – 2 = 33
In row 2, (8 × 6) – 2 = 48 – 2 = 46,
In row 3, (6 × 6) – 2 = 36 – 2 = 34,
Similarly in row 4, (8 × 7) – 2 = 56 – 2 = 54
Hence, 54 is the correct alternative.
sec^{2}θ + tan^{2}θ =53=53
[1 + tan^{2}θ = sec^{2}θ]
1 + tan^{2}θ + tan^{2}θ =53=53
2 tan^{2}θ = 5/3−1
tanθ =1/√3
∴ θ = 30°
A dishonest shopkeeper uses a weight of 850 gm instead of 1 kg and sells rice on its cost price. What will be his profit percentage on selling 5 kg rice?
Original weight of rice = 1 kg = 1000 gm
Let cost of 1 gm is Rs. 1
Cost price of 1000 gm = Rs. 1000
Selling price of 850 gm = Rs. 1000 (∵ giving only 850 gm instead of 1000 gm)
Profit = [error/ (true weight)] × 100
⇒ Profit = [(1000  850)/ 850] × 100 = (150/850) × 100 = 17.65%
∴ profit % on 5kg is equal to profit on 1 kg which is 17.65%
Some equations have been solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis.
If 95 + 65 + 23 = 81; 56 + 23 + 62 = 48 then 56 + 26 + 32 = ?
The pattern followed is:
95 + 65 + 23 = 81
9 × 5 + 6 × 5 + 2 × 3 → 45 + 30 + 6 = 81
Similarly;
56 + 23 + 62 = 48
5 × 6 + 2 × 3 + 6 × 2 → 30 + 6 + 12 = 48
Similarly;
56 + 26 + 32 = ?
5 × 6 + 2 × 6 + 3 × 2 → 30 + 12 + 6 = 48
Hence, 48 is the correct answer.
The product of HCF and LCM of two numbers is 2535. The smaller number is 60% of the larger number. Find the difference of between the numbers.
Let the first number be 5a.
So, the second number = 60% of 5a = 3/5 × 5a = 3a
HCF × LCM = 1^{st} no. × 2^{nd} no.
⇒ 2535 = 5a × 3a
⇒ 2535 = 15a^{2}
⇒ a^{2 }= 169
⇒ a = 13
∴ Difference between the numbers = 5a  3a = 2a = 2 × 13 = 26

⇒ 3/4 = 0.75
⇒ 5/12 = 0.4167
⇒ 13/16 = 0.8125
⇒ 16/29 = 0.5517
⇒ 3/8 = 0.375
∵ 0.375 < 0.4167 < 0.5517 < 0.75 < 0.8125
∴ 3/8 < 5/12 < 16/29 < 3/4 < 13/16

I) Shifa is the daughter of Taimur.
We can’t determine relation between Shifa with Azad as Azad is not mentioned here.
II) Azad is the child of Amreen, who is the wife of Taimur.
We can’t determine relation between Shifa with Azad as Shifa is not mentioned here.
But, when combined together, we get
As the gender of Azad is not determined, we cannot say whether he is the sister or brother of Shifa.
Hence, the data even in the both statements I and II together are not sufficient to answer the question.

P can do a piece of work in 20 days and Q can do the same piece of work in 60 days. They start working together and work for 5 days and then both leave the work. R alone ﬁnishes the remaining work in 10 days. In how many days will R alone ﬁnish the whole work?
Work done by P in 1 day = 1/20
Work done by Q in 1 day = 1/60
Work done P and Q in 1 day = 1/20 + 1/60 = 1/15
Work done by P and Q in 5 days = 5 ⨯ 1/15 = 1/3
∴ P and Q finished 1/3^{rd} of the work in 5 days.
R finished 2/3^{rd} of the work in 10 days
2/3 work = 10 days
1 work = 10 × (3/2) = 15 days
∴ R will finish the whole work in 15 days.

The sharp pain caused by the sting of an ant is due to ________.
A man sells an article at 10% above its cost price. If he had bought it at 10% less than what he paid for it and sold it at Rs 11 less, he would have gained 10%. The cost price of the article is∶
Let the cost price of the article be 100 unit
So, SP of the article = 100 × 110/100 = 110 unit
If he had bought it at 10% less, then new CP of the article = 100 × 90/100 = 90 unit
If he had paid for the article Rs. 11 less, he would have gained 10%
According to the question
⇒ (90 × 110/100) unit = 110 unit – 11
⇒ (110 – 99) unit = 11
⇒ 11 unit = 11
⇒ 100 unit = 100
∴ Cost price of the article Rs. 100

Newton’s second law of motion gives us the magnitude of ________.
If the amount received at the end of 2nd and 3rd year at Compound Interest on a certain Principal is Rs 1,800, and Rs 1,926 respectively, what is the rate of interest?
Let the principal be P
⇒ P(1 + r/100)^{2} = 1800
⇒ 1 + r/100 = √(1800/P) (i)
Also, P(1 + r/100)^{3} = 1926
⇒ 1 + r/100 = (1926/P)^{1/3} (ii)
⇒ √(1800/P) = (1926/P)^{1/3}
⇒ P = 1572
Putting the value of P in (i), we get
⇒ 1 + r/100 = √(1800/1572)
⇒ 1 + r/100 = 1.07
⇒ r/100 = 0.07
∴ r = 7%

⇒ H + 2 = J; J + 2 = L; L + 2 = N; N + 2 = P
Hence, U45P will be the next term.
A and B together have six times the sum what B and C together have, while A, B, and C together have Rs. 30 more than the sum that A has. If B has four times the sum than that of C, the sum A has, is approximate –
Given,
A and B together have six times the sum what B and C together have
∴ A + B = 6(B + C)…..(1)
A, B and C together have Rs. 30 more than the sum that A has
∴ A + B + C = A + 30
⇒ B + C = 30…..(2)
B has four times the sum than that of C.
∴ B = 4C…..(3)
Using (2) and (3)
4C + C = 30
⇒ 5C = 30
⇒ C = Rs. 6
Putting this in (2)
B + 6 = 30
⇒ B = Rs. 24
Putting value of B and C in (1)
A + 24 = 6(24 + 6)
⇒ A = 180 – 24 = Rs. 156
The oil used in the flotation method for the purification of ores is ________.
Which of the following potassium compounds is known as 'Pearl ash'?
Find the ratio of third proportional to 12 and 30 and fourth proportional to 11, 15 and 33.
We know that,
Third proportional to a and b = b^{2}/a
∴ Third proportional to 12 and 30 = (30)^{2}/12 = 900/12 = 75
We also know that,
Fourth proportional to a, b, c is given by = (b × c)/a
∴ Fourth proportional to 11, 15, 33 = (33 × 15)/11 = 45
∴ Ratio of Third proportional to 12 and 30 and Fourth proportional to 11, 15 and 33 = 75 : 45 = 5 : 3

On what principle, the difference between compound and simple interest shall come out to be Rs. 366, if the money is kept for 3 years at 5%?
Let the principal = Rs. 100
Now, S.I. on Rs. 100 = PTR/100
Thus, S.I. on Rs. 100 = Rs. 15
⇒ C.I. on Rs. 100 = Rs. 15.7625
Now, the difference of C.I. and S.I. = 15.7625 – 15 = 0.7625
⇒ For Rs. 100 the difference in C.I. and S.I. is Rs. 0.7625
⇒ For Rs. X the difference in C.I. and S.I. is Rs. 366
∴ On Rs. 48000, the difference of compound and simple interest, shall come out to be Rs. 366

5000n = 5900n  59na
59na = 900n
a = 900n/59n
a = 15.25
By 15.25% new number should be decreased to obtain new number.

Combining I and II, we get two possible orders:
S, R, T, P, Q or S, P, R, T, Q.
Thus, either P or T is at the penultimate position.
A train passes an electrical pole in 30 seconds and passes a platform 240 m long in 2 Minutes. Find the length of the train:
Let the length of the train be D metres and speed of the train be S m/s
Now As per the basic formula of speed,
S = D/T
Where S = Speed, D = Distance, T = Time
As the train passes an electric pole in 30 seconds
S = D/30 ........eq(i)
As train passes a platform 240 m long in 120 seconds
S = (D + 240)/120 .....eq(ii)
from eq(i) and (ii) we get
D/30 = (D + 240)/120
∴ 4D = D + 240
∴ 3D = 240
∴ D = 80 m

________ has won the award for the Best Supporting Actor at the Golden Globe Awards for 2019.
The question consists of two statements, an assertion, and a reason. The student must first determine whether each statement is true. Each question below consists of an assertion and a reason.
Assertion (A): Mahatma Gandhi is the Father of the Nation (India).
Reason (R): Gandhi’s picture is printed on the Indian currency notes.
It is true that Mahatma Gandhi is the Father of the Nation of India and hence, A is true. It is also true that Gandhi’s picture is printed on the Indian currency notes, so R is also true. But Gandhi is the Father of the Nation because of his contribution to the freedom struggle and only after that was his picture printed on the currency notes. Therefore, R is not the correct explanation of A and option 2 is the correct solution.

The side mirrors of vehicles are of which type of mirrors?
The side mirrors of vehicles are convex mirrors. Because the image is smaller, more space can be covered by this mirror, so a convex mirror provides for a larger field of view than a plane mirror. This is why they are used whenever a mirror with a large field of view is needed. For example, the passengerside rear view mirror on a car is convex.

If a + b + c = 8, a^{2} + b^{2 }+ c^{2 }= 30, and a^{3} + b^{3 }+ c^{3 }= 134, then the value of (abc)^{1} is:
Given, a + b + c = 8, a2 + b2 + c2 = 30 and a3 + b3 + c3 = 134
∵ (a + b + c)^{2} = a^{2} + b^{2 }+ c^{2} + 2(ab + bc + ca)
⇒ 8^{2} = 30 + 2(ab + bc + ca)
⇒ 2(ab + bc + ca) = 64  30
⇒ (ab + bc + ca) = 34/2 = 17
We know that,
∵ a^{3} + b^{3 }+ c^{3} – 3abc = (a + b + c) (a^{2} + b^{2 }+ c^{2} – (ab + bc + ca))
⇒ 134 – 3abc = 8 × (30 – 17) = 104
⇒ 3abc = 134  104 = 30
⇒ abc = 30/3 = 10
∴ (abc)^{1} = 1/10

The income of a person is Rs. 45000 and his expenditure is Rs. 33000. If his income is increased by 22% and expenditure increased by 11%, then what will be the percentage increase in his savings?
Initial income = Rs. 45000
Initial Expenditure = Rs. 33000
Savings = Rs. 45000  Rs. 33000 = Rs. 12000
New Income = 45000 + 22% of 45000 = Rs. 54900
New Expenditure = 33000 + 11% of 33000 = Rs. 36630
New savings = 18270
∴ Percentage increase in savings = [(18270  12000)/12000] × 100 = 52.25%
A boat goes 20 km against the stream and 32 km along the stream in 8 hours. It also goes 32 km against the stream and 20 km along the stream in 8.5 hours. What is the rate of the stream?
Let the rate of upstream be x kmph and rate of downstream be y kmph
Adding eq (1) and eq(2), we get
⇒ 52(1/x + 1/y) = 33/2
Subtracting eq (1) from eq(2), we get
⇒ 12(1/x – 1/y) = 1/2
Adding eq (3) and eq (4), we get
⇒ 2/x = 14/39
⇒ x = 5.57 kmph
⇒ Substitute x in eq (3), we get
⇒ 1/(5.57) – 1/y = 1/24
⇒ y = 7.25 kmph
Upstreamrate is 5.57 kmph and rate downstream is 7.25 kmph
∴ Rate of current = = 0.84 kmph
Two trees are standing along the opposite sides of a road. Distance between the two trees is 400 metres. There is a point on the road between the trees. The angles of depression of the point from the top of the trees are 45° and 60°. If the height of the tree which makes 45° angle is 200 metres, then what will be the height (in metres) of the other tree?
In the figure, H is the height of the other tree.
In triangle AEB, AB = 200/tan45°
⇒ AB = 200 mtr
⇒ BC = 400  200 = 200 mtr
In triangle DCB, tan 60° = H/BC
⇒ H = 200√3 mtr
∴ Height (in metres) of the other tree = 200√3 mtr

Akash purchased an article at a discount of 40% and sold it to Ram at 40% profit. What is the ratio between the market price and the price for which he sold?
Let, marked price = Rs. x
Discount = 40%
∴ Cost price = x  x × 40/100 = Rs. 0.6x
Profit = 40%
∴ Selling price,
⇒ 0.6x + 0.6x × 40/100
⇒ 0.84x
∴ Required Ratio,
⇒x ∶ 0.84x
⇒ 100 ∶ 84
⇒ 25 ∶ 21
Who among the following won the BWF World Championship 2018 women’s singles title?
A batsman scores 87 runs in the 21st match of his career. His average runs per match increases by 2. What was his average before the 21st match?
Let his average before the 21^{st} match be x and average after the 21^{st} match will be x + 2
His total runs before the 21^{st} match can be given as 20x.
From the problem statement
⇒ x + 2 = (87 + 20x)/21
⇒ x = 45
∴ His average before the 21^{st} match is 45.

A circle and a rectangle have the same perimeter. The sides of the rectangle are 18 cm and 34cm. The approximate area of the circle is :
Perimeter of the circle = Perimeter of the rectangle
Perimeter of the circle = 2 × (length + breadth)
Perimeter of the circle = 2 × (18 + 34) = 104 cm
2πr = 104
r = 16.5 cm
Area of the circle = π × r^{2} = π × 16.5^{2} = 856 cm^{2}
∴ The area of the circle is 856 sq.cm
