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 |

Why do we have to add 8 to 5/2 of x yet it was after 8 years?
So, 4x+8 =5x/2.
So, 4x+8 =5x/2.

In the question, son's age is 2 (1/2) age.
So, 2x1/2 is 5/2fraction form.
So, 2x1/2 is 5/2fraction form.

(4x + 8) = 2.5(x + 8).
4x + 8 = 2.5x + 20 and equation multiplied by 2.
4x + 8 = 2.5x + 20 and equation multiplied by 2.
