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 |

Consider son's age as 'x'
so they have said,
Father is aged three times more than his son
as per the statement, x+3x
after 8ys ,he would be 2 and a half times of his son
so, x+3x+8=x+8
4x+8=x+8
(4x+8)=5/2(x+8)
we get, 8x+16=5x+40 => 3x=24
x=8
after further 8 years,
so add 8 to the equation 4x+8+8=x+8+8
4x+16=x+16
so the ratio is, (4x+16)/(x+16) = 48/24
=> 2years
Got it friends?

(4x + 8) = 5 (x + 8)

8x + 16 = 5x + 40
how this 16 came

Its 3x + x = 4x. Because its 3 times more not only 3 times.
