Jais and his father has an age difference of 35 years now. After 5 years, the sum of their age is 125. What will be the age of Jais and his father after 12 years from now?
-
- 51 and 85
- 52 and 87
- 40 and 75
- 45 and 70
Correct Option: B
Suppose the age of Jais = P years
The age of his father - The age of Jais = 35 years
Therefore, his father’s age = P + 35 years
According to question ,
After 5 years,the sum of their age is 125.
⇒ (P + 5) + (P + 35 + 5) = 135
⇒ 2P + 45 = 135
⇒ 2P = 135 – 45
| ∴ P = | = 45 | 2 |
Age of Jais after 12 years = P + 12 = 40 + 12 = 52 years
Age of his father after 12 years = 40 + 35 + 12 = 87 years
