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 itself the ages are 6x, 5x respectively. Then hence 6 years it becomes 6x+6, 5x+6 right?

If it is 6 years ago, the ratio should be subtracted by 6. Why is it added here? Can anyone explain?

Why we subtract 6 years from answer. Because we find answer for 6 years ago and also 4 years hence?

Clearly giventhat, 6 years ago the ratios of ages of kunal and sagar was 6:5, so we have to add 6.

6 years ago means we have to subtract as per the formula. Then why did they add in this problem?

I don't know why 6 is added here, because here it is given ago.
So, please tell me, anyone.

They asked after four year, why we put the x=5. So we can add x=4. Answer me please.

(x-6)/(y-6)=6/5 ---> i
(x+4)/(y+4)=11/10 ---> ii
By solving i and ii , we get y=16.
(x+4)/(y+4)=11/10 ---> ii
By solving i and ii , we get y=16.

What is the differece between "ago" and "hence" if at the both times 6 was added?

I just can't understand please explain how (6x + 6) + 4 = 11 / (5x + 6) + 4 = 10.
