### Question 3

### Question 4

The ratio of ages of P and Q today is ${1/2}$. After 4 years, their ages will be in the ratio ${7/10}$. What is the age of P today?

### Question 5

The sum of reciprocals of my ages 2 years back and 2 years later is ${70/1221}$. What is my present age?

**A**

35 years.

**B**

36 years.

**C**

34 years.

**D**

37 years.

**Soln.**

**Ans: a**

Let the present age be x. Then $1/{x + 2} + 1/{x - 2}$ = ${70/1221}$. 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 ${2x}/{x^2 - 4}$ = ${70/1221}$. This can now be solved to give x = 35 years.
