Question

ajay is elder than Vijay by 5 years. sum of their ages is 35 years.What is Ajay's age?

Answer 1

let the age of ajay =x

let the age of vijay =y

A.T.Q.

x=y+5---------(1)

x+y=35----------(2)

putting the value of eqn. (1) in eqn. (2)

y+5+y=35

2y+5=35

2y=30

y=15

putting the value of y in eqn. (1)

x=15+5

x=20

so, the age of ajay is 20 years.

Answer 2

let the age of vijay be = x

let the age of ajay be = x + 5

x + x + 5 = 35

2x + 5 = 35

2x = 35 -5

2x = 30

x = 30/2

x = 15

so, age of vijay is = 15 years

age of ajay is = x +5 = 15 + 5 = 20 years
