### Question 1

My present age is 1443 times the reciprocal of my age 2 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 $x = 1443/{x - 2}$. 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 $x × (x - 2)$ = 1443. This can now be solved to give x = 39 years.

### Question 2

My father was 20 years old when I was born. My mother's age was 19 when my sister, who is 5 years younger to me, was born. What is the difference between the ages of my parents?

**A**

6 years.

**B**

7 years.

**C**

5 years.

**D**

8 years.

**Soln.**

**Ans: a**

If the age of my father is F, then my age is F - 20, so my younger sister's age is (F - 20) - 5, which is = F - 25. If my mother's age is M, then M = (my sister's age) + 19, i.e., M = (F - 25) + 19. We get F - M = 6 years.

This question can be solved directly also. The age of my father at the time of birth of my sister was 20 + 5 = 25. At the time my mother was 19 years. So the difference between their ages = 25 - 19 = 6 years.

### Question 3

My present age is 1330 times the reciprocal of my age 3 years back. What is my present age?

**A**

38 years.

**B**

39 years.

**C**

37 years.

**D**

40 years.

**Soln.**

**Ans: a**

Let the present age be x. Then $x = 1330/{x - 3}$. 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 $x × (x - 3)$ = 1330. This can now be solved to give x = 38 years.

### Question 4

Mr. X became a voter at the age of 18. He got married at the age of 20. What was his average age during these two points of his life?

### Question 5

5 years back the ratio of ages of X and Y was $1{2/11}$. The ratio of their ages 5 years from now would be $1{1/8}$. What is the present age of X?

**A**

31 years.

**B**

32 years.

**C**

30 years.

**D**

33 years.

**Soln.**

**Ans: a**

Let their present ages be x and y. Then ${x - 5}/{y - 5} = $ ${13/11}$, which is same as: $1{2/11}$. Similarly, ${x + 5}/{y + 5} = $ ${9/8}$, which is same as: $1{1/8}$. Solving these equations for x and y, we get y = 27, and x = 31 years as the answer.
