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 |

It's so simple!
The value of x is ''8'' so 4 x is (4(8) + 16)/(8 + 16) and you get 48/24 = 2.

Here, 2 and a half means 2.5.
So, 5/2 = 2.5.
Example: 3.5 means 7/2. Hope you get it.

It is clearly mentioned two and half times. Therefore 2and 1/2.
i.e., (2*2+1) /2 = 5/2.
i.e., (2*2+1) /2 = 5/2.

2 and 1/2 == 5/2.
Since given "of Ronit's age", therefore multiply 2/5 to Ronit's age.
