**Question:**

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? (A) 16 (B) 18 (C) 20 (D) 15

16 yrs

__16__

16

16-6 can be divided by 5 and 16+4 can be divided by 10...so answer is 16

__16__

__A__

Let ages 6 years back

6x and 5x

Then

(6x+6+4)/(5x+6+4)=11/10

10(6x+10)=11(5x+10)

5x=10

x=2

Sagar present age (5x+6)=(5*2)+6=16

@akhikesh bhai solve kaise __kiya__

Time =10 yrs Note-before, before=-

later,later=-

before,later=+

later,before=+

These are for time

Now, 6:5

11:10

10,10

So age of sagar=(11×10-10×10)/(10×6-10×5)×5+6

=16 yrs

A is correct
