Question : 1

At present, P is 4 years elder than Q. If after 2 years the ratio of the ages of P and Q will be 5 : 4, then what will be the age of Q after 2 years?

a) 8 years

b) 16 years

c) 20 years

d) 24 years

e) 10 years

Answer: (b)

Let ages of P and Q after 2 years will be 5x years and 4x years respectively

According to question

5x – 4x = 4 ⇒ x = 4

Hence, the age of Q after 2 years = 4x

= 4 × 4

= 16 years.

Question : 2

Two people A and B spend 30% of their income if their total expenditure is Rs. 26400 and the income of A is 20% more than B, what is the income of B?

a) Rs. 40000

b) Rs. 36000

c) Rs. 24000

d) Rs. 30000

e) Rs. 48000

Answer: (a)

Let the income of B = Rs. 100x,

then the income of A = 100x + 20% of 100x

= Rs. 120x

Total expenditure of A and B = 30% of (100x + 120x)

= 66x

According to question 66x = 26400

⇒ x = $26400/66$ = 400

Hence, the income of B = 100x

= 100 × 400

= Rs. 40000

Question : 3

Two people A and B invest an equal amount in a scheme for t and (t + 4) years respectively. If the ratio of the simple interest earned by A and B is 1 : 2, then what is the value of t?

a) 8

b) 1

c) 2

d) 4

e) 5

Answer: (d)

Let each of A and B invested Rs. 100 and the rate of interest = 1%, then

Simple interest of A = $\text"100x1xt"/100$

= $t(SI = \text"PRT"/100)$

Simple interest of B = $\text"100x1x(t+4)"/100$

= $(t+4)(SI = \text"PRT"/100)$

According to question =$t/1 = \text"t+4"/2$

⇒ t = 4

Study the following data carefully and answer the questions accordingly.
