Solution:

71+x + 71-x = 50

7(7x) + 7/7x = 50

From the options, the possible value of x should be 1 since the whole equation equals 50.

To check the same:

If x = 1, 7 (7) + 1 = 49 + 1 = 50

If X = -1, 7/7 + 7/7-1 = 1 + (7)(7) = 1 + 49 = 50

So the value of x is

$$\pm 1$$

Question 186. A man’s salary is reduced by 10%. In order to have his salary back to the original amount it must be raised by-

4. d.
$$12\frac{3}{7}%$$

Solution:

Let the salary of the person be ₹ 100.

10 % of ₹100 is ₹10.

New salary after reducing 10 % = ₹90

Let the percentage raise required to increase ₹10 be a%.

So, 90 * a / 100 = 10 (Note: the new percentage is calculated on the new salary ₹90)

a = 100 / 9 =

$$11\frac{1}{9}%$$

Question 187. 10% of 15% of 20% of Rs.500 is

=

$$\frac{1}{10}\times \left ( \frac{3}{20}\times \left ( \frac{1}{5}\times 500 \right ) \right )$$

=

$$\frac{1}{10}\times \left ( \frac{3}{20}\times 500 \right )$$

=

$$\frac{1}{10}\times 15$$

= 3/2 = Rs. 1.50

Question 188. A shopkeeper purchases 11 pens for Rs. 10 and sells them at the rate of 10 for 11, then profit percent is;

1. a. 18%
2. b. 19%
3. c. 20%

Solution:

11 pens were bought for Z10.

Cost price of 1 pen = 10/11

Selling price of 10 pen = 11

Selling price of 1 pen = 11/10

$$Profit\: Percentage = \frac{Profit}{Selling\: Price} \times 100$$

$$\left ( \frac{\frac{11}{10}-\frac{10}{11}}{\frac{10}{11}} \right ) \times 100$$

$$\frac{\frac{121-100}{110}}{\frac{10}{11}} \times 100$$

$$\frac{21}{100}\times 100$$

= 21%

Question 190. If A’s income is 20% more than B. Then, B’s income is-

1. a. Same as A’s
2. b. 20% less than A’s
3. c.
$$16\tfrac{2}{3}$$
% less than A’s
4. d. 15% less than A’s

Solution:

If B’s income is Rs. 100.

A’s income is 20%. 20% of Rs. 100 is Rs. 20.

The income of A = Rs. 100 + Rs. 20 = Rs. 120.

To find what percentage of Rs. 120 is Rs. 20:

Rs. 120 * x/100 = Rs. 20

x = 200/12 = 50/3 =

$$16\tfrac{2}{3}$$
%

So, B’s income is

$$16\tfrac{2}{3}$$
% less than A’s income.

The probability of getting 53 sundays is 2/7.

Question 192. The minimum value of sinθ cosθ is

1. a. 0
2. b. -1
3. c. -½
4. d. ½

Solution:

Sin2θ = 2Sinθ cosθ

(1/2) (Sin2θ ) = Sinθ cosθ

The minimum value of Sinθ cosθ = ½ (-1) = - ½

(Since minimum value of Sin2θ = -1)

Question 193. When (1012 - 1) is divided by 111 the quotient is;

1. a. 90009009
2. b. 9009009009
3. c. 9000009
4. d. 900000009

Solution:

The value of 1012 will be a 13 digit number with 12 zeros. So, 1012 - 1 will be a 12 digit number with all the numbers 9. The number with maximum digits in the given options is 9009009009 (10 digits).

9009009009 x 111 = 999999999999, i.e., So the quotient is 9009009009.

Alternate method:

(1012 - 1) = ((106)2 - 12) = (1000000 + 1) (1000000 - 1) = (1000001)(999999)

(1012 - 1)/111 = (1000001)(999999)/(111)

= (10001)(9009)

= 9009009009

Question 194. If log 3x+4 = log 729 the value of x will be

1. a. 3
2. b. 1
3. c. 6

Solution:

log 3x+4 = log 729

log 3x+4 = log 36

So, x + 4 = 6

x = 6 - 4 = 2

Question 195. If p persons working p hours a day for each of p days produce p units of works, then the units of work produced by q persons working q hours a day each q day is

1. a. q3/p2
2. b. q2/p3
3. c. p2/q2
4. d. p3/q2

Solution:

p persons work for p hours for each of p days to produce p units:

Total man hours of work by p persons = p persons x p days x p hours = p3

q persons work for q hours for each of q days:

Total man hours of work by q persons = q persons x q days x q hours = q3

Number of units produce in p3 man hours = p units

Number of units produced in q3 man hours = (q3 x p)/p3 = q3/p2

Question 196. If x100 + 2x99 + k is fully divisible by (x+1) then value of k will be

1. a. 7
2. b. -3
3. c. 2
4. d. 1

Solution:

x + 1 is a factor of x100 + 2x99 + k.

So, x + 1 = 0

x = -1, is the zero of x100 + 2x99 + k

". (-1)100+ 2(-1)99 + k = 0

1 - 2 + k = 0

k = 1

Question 197. If radius of a right circular cylinder is increased by 10%, then by what percent it height should be decreased so that its volume remains unchanged

1. a. 17.26%
2. b. 17.36%
3. c. 17.46%
4. d. None of these

Solution:

Let’s take the radius and height of the cylinder as 10 units and 10 units respectively.

Volume of the cylinder = 𝜋(102)(10) = 1000𝜋 cu units. If the radius increases by 10%:

𝜋(112)(New height) = 1000𝜋

New height = 1000/121 = 8.264

Percentage change in height = (10 - 8 264 / 10) X 100 = 1.736 x 10 = 17.36%

Question 198. If

$$\sqrt{x+1} - \sqrt{x-1} = 1$$
, then value of x is

1. a. 5/4
2. b. 2/3
3. c. 4/5
4. d. 3/5

Solution:

$$\sqrt{x+1} - \sqrt{x-1} = 1$$

Squaring both sides
(x+1)+(x-1)-2√(x2-1) = 1
or 2x - 1 = 2√(x2-1)
Again squaring both sides
42 + 1 - 4x = 4(x2 - 1)
5 = 4x
x= 5/4

Question 199. There are thirty cards numbered from 1 to 30. If a card is drawn at random find the probability that, the drawn card has a prime number-

1. a. 1/2
2. b. 1/3
3. c. 1/4
4. d. 1/5

Solution:

The prime numbers from 1 to 30 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.

There are 10 prime numbers between 1 to 30.

Total number of possible chances = 30

Total number of favourable chances = 10

Probability of a card drawn from 1 to 30 having a prime number = 10/30 = ⅓
