Question

20. Anwar is 3 times as old as Babu. In 13 years, Anwar will be 1 year younger than twice Babu's
age. How old is Anwar now?
​

Answer 1

let Anwar's and babus age be x yrs

x=3x

in 13 years,

x+13=3x+13

Now anwar will be 1 year younger than twice babu s age,

2(x+13)=(3x+13)+1

2x+26=3x+14

2x-3x=14-26

-x= -12

x=12
so the age of anwar is 12×3=36 years
