Six years ago, the ratio of the ages of Kunal and Sagar was 6 : 5. Four years hence, the ratio of their ages will be 11 : 10. What is Sagar's age at present?
Answer: Option
Explanation:
Let the ages of Kunal and Sagar 6 years ago be 6x and 5x years respectively.
| Then, | (6x + 6) + 4 | = | 11 |
| (5x + 6) + 4 | 10 |
10(6x + 10) = 11(5x + 10)
5x = 10
x = 2.
Sagar's present age = (5x + 6) = 16 years.

6 years ago -> present -> after 4 years.
Their age are;
6x and 5x.
(6x + 6) and (5x+6).
Then ((6x + 6) + 4)) and ((5x + 6) + 4)).
Their age are;
6x and 5x.
(6x + 6) and (5x+6).
Then ((6x + 6) + 4)) and ((5x + 6) + 4)).

Always we need to substract if it is given ago.
So mounika's answer is absolutely correct. The solution they gave is wrong.

Why we add 6 years instead of subtracting in some cases if we got 6 we are subtracting why in this we are adding 6?

6 year ago means x-n.
Current age = 6x-(6 year ago).
6x-(-6)+4 == 6x+6+4.
Hope you guys understood :).
Current age = 6x-(6 year ago).

Can u explain how (6x+6)+4, It will be (6x+4) right?
Because 4 years hence means we have to add (6x)+4.
Because 4 years hence means we have to add (6x)+4.
