Hema was twice as old as Geetha 10 years ago. How old is Geetha today if Hema will be 40 years old 10 years hence?
-
- 25 years
- 20 years
- 15 years
- 35 years
Correct Option: B
Suppose that the present age of Geetha is P years
10 years after , age of Hema = 40 years
Present age of Hema = 40 – 10 = 30 years
According to question
10 years ago , 2( present age of Geetha – 10 years ) = present age of Hema – 10
⇒ 2( P – 10 ) = 30 – 10
⇒ 2P – 20 = 20
⇒ 2P = 20 + 20 = 40
| ∴ P = | = 20 years | 2 |
Hence ,the present age of Geetha is 20 years .
