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 |

@Seema.
If still you are not understanding you can put value of x in equation of last part of the question.

5/2(x+8).
The ans is simple at present 2 1/2 +3=5/2 and present age is x and after 8 years +8 so (x+8).

When it is "three times more" why should we take (3x+x)? It can also be (3x+2x) or (3x+.5x)?

Hello @Sundar,
Please tell me how did you take [(4x + 16)/(x + 16))]this ratio.
(4x + 16)/(x + 16).

Why we have to add x=8 ? I think we have to substitute the the value of x. Can anyone explain?
