Answer 1

Answer:

Explanation:

Let, seema present age is x

So, Gaurav present age is (31-x)

After 10 years, seema's age be (x+10)

And Gaurav's age be (41-x)

Now, given equation

(x+10)/(41-x) = 8/9

9x+90 = 328-8x

9x+8x = 328-90

17x = 238

x = 14

So, present age of seema is 14

And, Gaurav present age is (31-14) = 17
