### Question 1

The sum of ages of two friends is 13, whereas the product of their ages is 42. What is the sum of squares of their ages?

### Question 2

The ages of three friends are in the ratio 19:2:3. What is the age of the youngest friend if the sum of their ages 5 years back was 129 years?

**A**

12 years.

**B**

13 years.

**C**

11 years.

**D**

14 years.

**Soln.**

**Ans: a**

Let the ages of three friends be 19r, 2r and 3r. The youngest of these is 2r. We have been given their sum 5 years back. So (19 + 2 + 3)r - (3 × 5) = 129. Solving, we get r = 6. The youngest is 2 × 6 = 12 years.

### Question 3

The ratio of present ages of two monuments A and B is $2{1/9}$. If the difference of their ages is 90, then what is the age of B?

**A**

81 years.

**B**

72 years.

**C**

63 years.

**D**

90 years.

**Soln.**

**Ans: a**

The ratio of ages of A and B is given as ${19/9}$, which is same as: $2{1/9}$. So we can write the present ages of A and B, respectively, as 19r and 9r years. The difference is $19r - 9r = 90$ which gives r = 9. The age of B, therefore, is 9r = 9 × 9 = 81 years.

### Question 4

The age of father tortoise is 14 times the age of his son. After 50 years his age will be 4 times the age of his son. What would be the ratio of their ages 180 years from today?

**A**

2.

**B**

5.

**C**

3.

**D**

4.

**Soln.**

**Ans: a**

If the age of the son today is s, the age of the father is 14s. After 50 years, we have 14s + 50 = 4(s + 50). Solving for s, we get s = 15 years. The ratio of their ages after 180 years = ${14s + 180}/{s + 180}$. Substituting s and simplifying we get the ratio as 2.

### Question 5

After 5 years from today the ages of three friends will be in an AP(arithmetic progression), and their sum would be 114. What is the age of the middle friend today?
