Question

annu is 20 years older than kapil in 5 years annu will be twice as old as kapil. find their present age?

Answer 1

annu - kapil=20-------1
a+5 =2(k+5)
a+5 =2k +10
a-2k =5-----------2
1-2
a -k -a +2k =20-5
k=15
a=20+15=35 yrs

Answer 2

let kapil be x then annu x+20
and A/Q in 5 years
2(x+5) = x+20+5 = x+25
solving for x we get x = 15
Therefore Kapil is 15 years old presently and annu is 35 years old
