Answer 1

Step-by-step explanation:

let ashok's age be x years.

let arvind's age be y years.

According to 1st condition

y =3x

According to 2nd condition

four years ago arvind's age (y-4)

four years ago ashok's age (x-4)

According to question

arvind's age = 4×ashok's age

(y-4)= 4(x-4)

put y =3x

3x-4= 4x-16

16-4=4x-3x

12=x

ashok's present age is 12 years

arvind's present age is 12×3 = 36 years
