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 solved in this way.
Per 8 years age decrease: (3x-5x/2) = x/2.
"1" " " x/16.
After 16 years = 16*x/16 = x.
3x-x = 2x.
After 16 years. So 2 times of Ronit's age. As father's age x.
Per 8 years age decrease: (3x-5x/2) = x/2.
"1" " " x/16.
After 16 years = 16*x/16 = x.
3x-x = 2x.
After 16 years. So 2 times of Ronit's age. As father's age x.

First time more than 3 years of his son's age, after 8 years 2 and 1/2 years of Ronit age. Then finally 2 times of his son's age.
If you observe 1/2 times decreasing in ratio so its only guess.

Son age = x.
Father age = 3x+x.
4x+8 = 2.5 (x+8).
4x+8 = 5/2 (x+8).
2(4x+8) = 5(x+8).
8x+16 = 5x+40.
8x-5x = 40-16.
3x = 24.
x = 8.
Now follow the rest.
Father age = 3x+x.
4x+8 = 2.5 (x+8).
4x+8 = 5/2 (x+8).
2(4x+8) = 5(x+8).
8x+16 = 5x+40.
8x-5x = 40-16.
3x = 24.
x = 8.
Now follow the rest.

What is that? Father's age is 3 times of Ronit so is it came 4x?

If, X = 8 than, when son was 8 father was 24.
When son was 16 father will be 32.
How 32 is 2.5 multiplier of 16?
When son was 16 father will be 32.
How 32 is 2.5 multiplier of 16?

Why will we add 8 + 8?

Please explain.
Father is aged three times more than his son Ronit.
Then why father age = x, and Ronit age is = x?
Why not father age = x? And son Ronit age = y.
