If the polynomial f(x) = x4  2x3 + 3x2  ax + b is divided by (x  1) and (x + 1), the remainders are 5 and 19 respectively. The values of a and b are ________
By remainder theorem,
f(1) = 5 (i)
[x  1 = 0, so x = 1]
f(  1) = 19 (ii)
[x + 1 = 0,so x =  1]
Now from eq.(i)
1  2 + 3  a + b = 5
Or b  a = 3 (iii)
From eq.(ii)
1 + 2 + 3 + a + b = 19
Or a + b = 13 (iv)
From eq. (iii) + (iv)
2b = 16
b = 8
Now from eq.(iv)
a = 13  8 = 5
a = 5 , b = 8

Weight of C is twice the weight of M. Weight of M is 1/9 of the weight of R. Weight of R is 5/2 of the weight of K. Weight of K is 1/3 of the weight of G. Who is the second lightest?
Let weight of M be x.
Weight of C is twice the weight of M → C = 2x
Weight of M is 1/9 of the weight of R → M = 1/9 R → R = 9x
Weight of R is 5/2 of the weight of K → 9x = 5/2K → K = 3.6x
Weight of K is 1/3 of the weight of G → K = 1/3G → 3.6x = 1/3G → G = 10.8x
Final solution is:
G > R > K > C > M
Hence, ‘C’ is the 2^{nd} lightest.

If the selling price of an article is doubled, then its loss percentage gets converted into the equal profit percentage. What is the loss percentage?
Loss % = {(Cost price – selling price)/cost price} × 100
Profit % = {(2 × selling price – cost price)/cost price} × 100
According to question,
{(Cost price – selling price)/cost price} × 100 = {(2 × selling price – cost price)/cost price} × 100
⇒ cost price – selling price = 2 × selling price – cost price
⇒ 2 × cost price = 3 × selling price
⇒ Selling price/cost price = 2/3
Now,
∴ Loss % = {(Cost price – selling price)/cost price} × 100 = {1 – (selling price/cost price)} × 100 = {1 – (2/3)} × 100 = 33.33%

In a triangle ABC, a line is drawn from C which bisects AB at point D. Find the ratio of the area of triangles DBC and ABC.
As (6, 8, 10) is a pythagorean triplet so triangle ABC is a right angled triangle, right angled at B
⇒ Area of triangle ABC = (1/2) × base × height = 1/2 × 6 × 8 = 24 cm2
Now, point D bisects AB
⇒ DB = (1/2) × AB = 1/2 × 8 = 4 cm
Also, triangle DBC is a right angle triangle, right angle at B
⇒ Area of triangle DBC = (1/2) × base × height = 1/2 × 6 × 4 = 12 cm2
∴ Required ratio = area of triangle DBC ∶ area of triangle ABC = 12 ∶ 24 = 1 ∶ 2
Manu gives 20% of his money to his eldest son, he gives 40% of the remaining to his youngest son, he gives 30% of the remaining to a school for poor boys. Still, he has Rs. 1008. Find his total sum.
Let’s assume that initially Manu has Rs.X
First he gives 20% of his money to his eldest son
∴ money given to the eldest son = 0.2 X
∴ Remaining money = X – 0.2 X = 0.8 X
Then he gives 40% of the remaining money to his youngest son
∴ money gives to the youngest son = 0.8 X × 0.40 = 0.32 X
∴ Remaining money = 0.8 X – 0.32 X = 0.48 X
Then he gives 30% of the remaining money to a school for poor boys
∴ money gives to school for poor boys = 0.48 X × 0.30 = 0.144 X
∴ Remaining money = 0.48 X – 0.144 X = 0.336 X
Given finally remaining money = 1008
∴ 0.336 X = 1008
⇒ X = 3000
∴ the total sum is = Rs. 3000

What would be the expenditure in 30 days at the rate of 75 paise per unit, if a bulb of 100 W is used five hours per day?
1 unit = 1 kWh
100 W = 0.1 kW [∵ 1kW = 1000 W]
In 30 days total consumption of the bulb = 0.1 kW × 30 days × 5 hours/day = 15 kWh
Given, cost of 1 unit = 75 paise
So total expenditure = 75 × 15 = 1125 paise = Rs. 11.25

A number M is divisible by 25. If (M + 5)(M + 1) is divided by 25, then what will be the remainder?
A number M is divisible by 25 if it ends with 00, 25, 50, or 75.
(M + 5)(M + 1) = M^{2} + 6M + 5
When a number (x + z) is always divisible by y, the remainder of (x + z) when divided by y will be zero
When M^{2} + 6M + 5 is divided by 25, the remainder will be due to sum of that.
M is divisible by 25, M^{2} is also divisible by 25
6M will also be divisible by 25
5 when divided by 25 leaves the remainder of 5
So the sum M^{2} + 6M + 5 is divided by 25, the remainder will be 5

In a Joint family of 4 males and some female members, all members are working and the average monthly income per head is Rs.21750; while the average monthly income of male members is Rs.24000 per head and for female members, it is Rs.18750 per head. The number of female members in the family is:
According to the given information,
Number of male members = 4
Let the number of female members be y.
We know that, Average = Sum of all observations/Number of observations
The average monthly income of male members is Rs.24000 per head
∴ 24000 = Total monthly income of males/4
⇒ Total monthly income of males = 24000 × 4 = 96000
The average monthly income of female members is Rs.18750 per head
∴ 18750 = Total monthly income of females/y
⇒ Total monthly income of females = 18750y
Now, total average monthly income = (Income of males + Income of females)/(males + females)
⇒ 87000 + 21750y = 96000 + 18750y
⇒ 3000y = 9000
⇒ y = 3
Hence, the number of female members is 3.
Amar started doing work, but left it after 6 days. Chetan completed the remaining work in 8 days. If Chetan alone can do the work in 24 days, how many days would Amar take to complete the remaining work?
1 day's work of Chetan = 1/24
8 days' work of Chetan = 8 × 1/24 = 1/3
Hence, the remaining work that Chetan completed in 8 days = 1/3
⇒ Work done by Amar in 6 days = 1 – 1/3 = 2/3
⇒ 6 days' work of Amar = 2/3
⇒ 1 day's work of Amar = 1/6 × 2/3 = 1/9
This means that Amar would have done the whole work in 9 days.
∴ Amar would have taken (9 – 6 = 3) days to complete the remaining work.

If by increasing the price of a ticket in the ratio 8 : 11 the number of tickets sold fall in the ratio 23 : 21 then what is the increase (in Rs.) in revenue if revenue before the increase in the price of the ticket was Rs. 36,800?
Let the price of the ticket be 8x and revised price be 11x (Since the ratio given is 8 ∶ 11)
Number of tickets sold be 23y and revised number be 21y,
⇒ Revenue before increase in price = 8x × 23y = 184xy
⇒ Revenue after increase in price = 11x × 21y = 231xy
Given, 184xy = 36800
⇒ xy = 200
⇒ Increased revenue = 231xy = 231 × 200 = Rs. 46200
∴ Increase in revenue = 46200  36800 = Rs. 9400

Members of which of the following have similar chemical properties?
3 boys and 4 girls can do a piece of work in 4.5 days. Also, 9 boys and 6 girls can do the same work in 2 days. In how many days will 6 boys and 8 girls finish the same work?
Let 1 boy’s 1 day work be ‘x’ and 1 girl’s 1 day work be ‘y’.
Hence, we have,
⇒ 3x + 4y = 1/(4.5)
⇒ 3x + 4y = 2/9 …(1)
Also,
⇒ 9x + 6y = 1/2 …(2)
Multiplying eq. (1) by 3 and subtracting from (2), we get,
⇒ 9x + 6y – 9x – 12y = 1/2– 2/3
⇒ – 6y = –1/6
⇒ y = 1/36
Substituting in (1),
⇒ x = 1/27
⇒ 6 boys and 8 girls 1 day work = 6(1/27) + 8(1/36) = 2/9 + 2/9 = 4/9
∴ 6 boys and 8 girls will finish the same piece of work in 9/4 days.

A shopkeeper bought wheat flour at a price of Rs. 20 per kg. Using faulty weights, he gives only 900 g to a customer instead of 1 kg. If he sells the wheat flour at Rs. 25 per kg, find his profit percentage.
Cost price of wheat flour = Rs. 20 per kg
Selling price of wheat flour = Rs. 25 per kg
Profit percentage due to price = [(25 – 20)/20] × 100 = 25%
He gives 900 g instead of 1 kg ( = 1000 g)
Profit percentage due to false weight = [error/(true weight – error)] × 100 = (100/900) × 100 = 11.1%

Directions: In making decisions about important questions, it is desirable to be able to distinguish between Strong arguments and Weak arguments. Strong arguments are those, which are both important and directly related to the question. Weak arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The question below is followed by two arguments numbered I and II. You have to decide which of the arguments a strong argument is and which a Weak argument is.
Statement: Should there be only one university throughout India?
Arguments:
I. Yes. It is the only way to bring uniformity in the education system of India.
II. No. Implementing this would not be possible.
It is not possible to have a single university in the whole country and uniformity can be achieved in other ways like following the same syllabus or pattern of questions. Thus only II holds.
A vendor sells 40% of his stock for a particular item and recovers the cost price. If he continues to sell rest of the stock at the same price, what will be his profit percentage after selling the complete stock?
⇒ Given: 40% of SP = 100% of CP
⇒ 1% of SP = 100% / 40% of CP
⇒ 100% of SP = 100% / 40% ⨯ 100% of CP
⇒ 100% of SP = 250% of CP
∴ Profit = SP  CP = (250  100)% = 150%
Match the following items of column (A) with column (B).
A certain bank offers 8% rate of compound interest on the 1st year and 9% on the 2nd year in a certain fixed deposit scheme. If Rs. 17,658 is received after investing for 2 years in this scheme, then what was the amount (in Rs) invested?
According to question,
17658 = P(1 + 8/100)(1 + 9/100)
⇒ 17658 = P × 108/100 × 109/100
⇒ P = Rs. 15000
∴ The amount invested = Rs. 15000
If it takes 20 seconds for a train to cross a 60 meters long platform, and a man standing on platform observes that it took 16 seconds for train to cross him. Find the speed of train.
Let the length of train be x meters.
The speed of train be y m/s.
Since, Train is crossing a man, so the distance travelled by train to pass a man is equal to its own length.
Now, as we know that Speed = Distance/Time
∴ y = x/16
⇒ x = 16y
While crossing the platform total distance covered by train would be summation of length of train and length of platform.
∵ Speed = distance/time
∴ y = (x + 60)/20
⇒ 20y = x + 60
⇒ x = 20y – 60
On equating value of x, we get
16y = 20y – 60
⇒ 4y = 60
⇒ y = 15 m/s.
⇒ y = kmph = 54 kmph
Speed of train is 54 kmph.
Which of the following sequence is difference form the rest?
The logic here is as follows,
1) 8, 20, 44, 92, 188
(2 × 2) + 4 = 8
(8 × 2) + 4 = 20
(20 × 2) + 4 = 44
(44 × 2) + 4 = 92
(92 × 2) + 4 = 188
2) 6, 16, 36, 76, 156
(1 × 2) + 4 = 6
(6 × 2) + 4 =16
(16 × 2) + 4 = 36
(36 × 2) + 4 = 76
(76 × 2) + 4 = 156
3) 4, 12, 28, 60, 124
(0 × 2) + 4 = 4
(4 × 2) + 4 =12
(12 × 2) + 4 = 28
(28 × 2) + 4 = 60
(60 × 2) + 4 = 124
4) 7, 22, 67, 202, 607
(2 × 3) + 1 = 7
(7 × 3) + 1 = 22
(22 × 3) + 1 = 67
(67 × 3) + 1 = 202
(202 × 3) + 1 = 607
Thus the odd series is 7, 22, 67, 202, 607.

The animals in which the body cavity is absent are known as _______.
Animals that have a body cavity called a coelom with a complete lining called peritoneum derived from mesoderm (one of the three primary tissue layers) are called Coelomates (also known as eucoelomates  "true coelom"). Contrarily, animals which lack a coelom, like flatworms and tapeworms, are called acoelomates.
Which state's 'Katarni rice' got the Geographical Indication (GI) tag?
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. In general, impedance will be a complex number, with the same units as resistance, for which the SI unit is the ohm (Ω).
Stress is defined as the force per unit area of a material. i.e.
Stress = force/cross sectional area:
where, sigma (σ)= stress, F= force applied, and A = cross sectional area of the object.
Units of stress : Nm^{2} or Pa.
Refer the below data table and answer the following question :
Q. What was the total profit or loss of the company in the last 5 years?
Total profit = Rs. (5 + 15) crore = Rs. 20 crore.
Total loss = Rs. (15 + 15 + 10) crore = Rs. 40 crore.
∴ The net loss = Rs. 40  20 crore = Rs. 20 crore.
If 4 * 7 * 6 = 698 and 3 * 5 * 0 = 572, then 6 * 2 * 1 = ?
In 4 * 7 * 6 = 698
The pattern followed here is,
4 + 2 = 6
7 + 2 = 9
6 + 2 = 8
In 3 * 5 * 0 = 572
3 + 2 = 5
5 + 2 = 7
0 + 2 = 2
Similarly, then adding 2 to each number 6 * 2 * 1
6 + 2 = 8
2 + 2 = 4
1 + 2 = 3
Therefore, “843” is correct answer.
A, B, and C are three points on a circle. The tangent AT meets the extended chord BC at T such that ∠BTA = 44°, ∠ABC = ∠CAT = 40°. The angle subtended by BC at the center of the circle is 
⇒ Given: ∠CAT = 40° and ∠CTA = 44°
⇒ We have ∠CAT = ∠ABC = 40° (alternate segment of the circle)
⇒ Again, ∠BCA = ∠CAT + ∠CTA = 40° + 44° = 84° (exterior angle of a triangle)
⇒ Now , In ∆ABC,
⇒ ∠ABC + ∠BCA + ∠CAB = 180°
⇒ 40° + 84° + ∠CAB = 180°
⇒ ∠CAB = 56°
⇒ Again ∠BOC = 2∠CAB = 2 × 56° = 112° (angle subtended by a chord on the center is double to the angle subtended on the circle)

When the price of sugar decreased by 10%, a man could buy 1 kg more for Rs. 270. Then, the original price of sugar per kg is
Let the original price of the sugar per kg be Rs. X. Let the quantity of sugar purchased initially be Y units in Rs. 270.
Thus, X × Y = 270 ….(1)
Given: Price of sugar decreased by 10%.
∴New price of sugar per Kg =
= 0.9X
Since the man could buy 1 more kg on his reduction of price, hence
⇒ Quantity of sugar purchased = Y + 1
As the total expenditure remains the same i.e. Rs. 270, therefore
⇒ 0.9X × (Y + 1) = 270 …(2)
Dividing equation (1) by (2), we get
⇒ Y = 0.9Y + 0.9
⇒ Y = 9 units
∴ From equation (1) we get, X = Rs. 30
