1.
Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After further 8 years, how many times would he be of Ronit's age?
Answer: Option
Explanation:
Let Ronit's present age be x years. Then, father's present age =(x + 3x) years = 4x years.
 |
(4x + 8) = | 5 | (x + 8) |
| 2 |
8x + 16 = 5x + 40
3x = 24
x = 8.
| Hence, required ratio = | (4x + 16) | = | 48 | = 2. |
| (x + 16) | 24 |

(4x+8)=5/2(x+8) => 8x+16 = 5x+40
bcoz :
cross multiply : 2(4x+8) = 8x+16
straight multiply: 5(x+8) = 5x+40
Everyone clear.........

Hi vaishu,
