Question

sheela is now 15 years older than her yonger brother Sanjay ten years from now sheela will be twice as old as sanjay find the present age of each

Answer 1

Let Sanjay's present age = x
then Sheela's prsent age = x + 15

after 10 years Sanjay's age = x+10
after 10 years Sheela's age = x+15+10 = x+25

by question, after 10 years
x+25 = 2 (x+10)
x + 25 = 2x + 20
2x-x = 25-20
x=5
Hence Sanjay"s present age= 5 yrs Ans.
Sheela's present age = 5+15= 20yrs. Ans.
