Question

Suma is 15 years older than Vivek. Three years from now, Suma's age will be 8 times that of Vivek's age 3 years back. What is the PRESENT AGE of Vivek?

Answer 1

Answer:

let viveks age be = x

suma's age = x + 15

Three years from now suma's age is 8 times of viveks's age 3 years back that is

( x + 15) + 3 = 8( x - 3)

x + 15 + 3 = 8x - 24

x + 18 = 8x -24

18 + 24 = 8x - x.

7x = 42

x = 42/7= 6

Hence viveks age is 6 years

suma's age = 15+ 6= 21 years
