# 10 years age the age of Sachin was twice the age of Ajaya :

10 years age the age of Sachin was twice the age of Ajaya. If 10 years hence, Sachin will be 40 year old, then what is the present age of Ajaya?

- 20
- 10
- 30
- 15

**Answer: (1) 20 **

**Explanation:-**

Let the present age of Sachin be X years.

If the 10 years hence, Sachin will be 40 years old.

Then,

X + 10 = 40

X = 40 – 10

X = 30

So, the present age of Sachin is 30 years.

10 years ago the age of Sachin was twice the age of Ajaya.

Then 30 – 10 = 2 (Ajaya – 10)

20 = 2 Ajaya – 20

2 Ajaya = 40

Ajaya = 40/2

Ajaya = 20 years

Then the present age of Ajaya is 20 years.

Hence, the correct answer is option (1) 20 years.
