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 |

I think we should take father's age be y.
So x+8 is equal to (3y+8)5/2
So x+8 is equal to (3y+8)5/2

Father age is 3 times in starting.
After 8 year father age will be 2 and half times of son.
Means after 8 year father age decrease 1/2 times.
i.e. 3-(1/2)=2(1/2)
So, after 16 year father age will be= 2(1/2)-(1/2) = 2 times of son.
After 8 year father age will be 2 and half times of son.
Means after 8 year father age decrease 1/2 times.
i.e. 3-(1/2)=2(1/2)
So, after 16 year father age will be= 2(1/2)-(1/2) = 2 times of son.

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

Hi @Annapoorna,
It is supposed of x years for son and in question father is more than 3 years of son so that it is of (3x+x). Thanks.

How do we get (4x + 16) divide by (x + 16) instead of (4x+16)=(x+16)?

There are times when we take x & y both variable. So how to identify whether we have to use 1 variable or both?
