1.
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 |

(4x+8) is father's age.
2 and half is written as 5/2...i.e., (2 1/2 = ((2*2) +1)/2 => 5/2) (mixed fraction is converted into proper fraction).
(x+8) is ronit's age.
2 and half is written as 5/2...i.e., (2 1/2 = ((2*2) +1)/2 => 5/2) (mixed fraction is converted into proper fraction).
(x+8) is ronit's age.

Hi Guys!
It is 4x not 3x. (As Krithika said).
If the given statement is "Father is aged three times of his son Ronit's age", then it will be 3x.
But, the given statement is "Father is aged three times more than his son Ronit". So, it should be 4x.
Some answers to your other doubts:
1. How 5/2 came? Ans: "Two and a half times" can be written as 2.5 or 5/2.
2. How 16 came? Ans: 8 Years + Further 8 Years = 16 years.
Have a nice day for all!
