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 |

Lovely please read question carefully..........
"At present age of father is (3)times more than his son"
(X=3)
"after 8 years age of father is (2 1/2)times more than his son"
(X= 2 1/2)
"AFTER 8 YEARS WHAT IS THE SONS AGE (i.e here, age of the son will be reducing half,gap of 8 years)"
So(X=2)
[1years->3times
8years->2 1/2times
16years->2times
24years->1 1/2times
32years->1times......................]

Hey we got the x value is 8. So just put the value of 8 in place of x and find out the ratio, you definitely get the answer.

If father's present age 37 year then what's the age of son ? please help me.

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.
