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.

I dont think what vinod said is right....
Faruk has clearly explained...6 years
hence i.e.,6 yrs before the ages pf kunal and sagar is 6x and 5x respectively...
So present ages of both are 6x+6 and 5x+6(since present,add 6 years)..you'11 get it..

(k-6)=(6/5)(s-6)-first statement
k+4=(11/10)(s+4)- second staement..is this eqn right..? this s how i calculte the problems based on ages i.e by writing an eqn for each statement and solving it..! i m not getting d answer by solving this two eqns..! wats wrong in it..?

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

It is clearly said that 6 years ago their age was 6:5, so and hence their present age will be (6x+6)/(5x+6) and hence after 4 years you have to add another 4.

In case of "ago" we always subtract the number of year.. But in the given answer.. its wrong I think.... as in next question on page 3 in case of "ago"... you also subtract the number of years.

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

Why we have added 6 years instead of deducting as it is given that 6 years ago?
