Question 618294
shila is 15 years older than her brother sanjay. ten years from now shila will be twice as sanjay. find their present ages
**
let x=sanjay's present age
x+15=shila's present age
10 years hence:
sanjay's age=x+10
shila's age=x+15+10=x+25
x+25=2(x+10)=2x+20
x=25-20=5
x+15=20
ans:
sanjay's present age=5
shila's present age=20
