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 |

Hi @Seema.
x = 8.
(4x+16)/(x+16) = 4*8+16.
= 24+16.
= 48.
= 8+16 = 24.
= 48/24.
= 2.
x = 8.
(4x+16)/(x+16) = 4*8+16.
= 24+16.
= 48.
= 8+16 = 24.
= 48/24.
= 2.

Actually the point is Ronit's father is more than 3 times. So 4x is absolutely right.

Guys! It's three times more that mean 4x if it would be three times then we used 3x.

Father can't comes to sons age i.e. Father can't come to Ronit's age. Have doubt in?

We already add 8 years....to get the x value then Why we add 16 yrs in second step.

Because it is asked to find out how many times would his father be of Ronith's age?

I think 3 times more than X means = 3X And three times less than X means = X/3.
