### Question 1

The ages of two friends are 4 and 9 years respectively. They are looking for a special third friend whose age is in-between their ages. What should be the age of the third friend if the ages of all three have to be in a GP(geometric progression)?

### Question 2

The sum of reciprocals of my ages 2 years back and 2 years later is ${74/1365}$. What is my present age?

**A**

37 years.

**B**

38 years.

**C**

36 years.

**D**

39 years.

**Soln.**

**Ans: a**

Let the present age be x. Then $1/{x + 2} + 1/{x - 2}$ = ${74/1365}$. 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 ${2x}/{x^2 - 4}$ = ${74/1365}$. This can now be solved to give x = 37 years.

### Question 3

P is 10 years older than Q, and Q's age is 7 times the age of R. If the sum of their ages today is 85, then what is the age of Q?
