### Question 1

The ages of three friends are in the ratio 2:3:17. What is the age of the youngest friend if the sum of their ages 3 years back was 35 years?

### Question 2

The ages of three friends are in the ratio 17:5:13. What is the age of the youngest friend if the sum of their ages is 105 years?

### Question 3

My present age is 1287 times the reciprocal of my age 6 years back. What is my present age?

**A**

39 years.

**B**

40 years.

**C**

38 years.

**D**

41 years.

**Soln.**

**Ans: a**

Let the present age be x. Then $x = 1287/{x - 6}$. At this stage a better option is that you try putting the given answers into this expression one by one. The other option is to simplify this expression into a quadratic equation $x × (x - 6)$ = 1287. This can now be solved to give x = 39 years.

### Question 4

The ratio of present ages of two monuments A and B is $5{1/4}$. If the difference of their ages is 136, then what is the age of B?

**A**

32 years.

**B**

28 years.

**C**

24 years.

**D**

36 years.

**Soln.**

**Ans: a**

The ratio of ages of A and B is given as ${21/4}$, which is same as: $5{1/4}$. So we can write the present ages of A and B, respectively, as 21r and 4r years. The difference is $21r - 4r = 136$ which gives r = 8. The age of B, therefore, is 4r = 4 × 8 = 32 years.

### Question 5

The ratio of ages of P and Q today is ${10/41}$. After 3 years, their ages will be in the ratio ${11/42}$. What is the age of P today?
