step by step explaination​

Answer 1

Answer:

Rajan: 45

Babu: 15

Step-by-step explanation:

let r be rajan and b be babu

1) r = 3b

2) r + 15 = 2(b + 15)

on substituting the value of r from first equation to second eqn, we get:

(3b) + 15 = 2(b + 15)

3b + 15 = 2b + 30

3b - 2b = 30 - 15

b = 15

substituting this value in eqn 1 we get:

r = 3b

r = 3(15)

r = 45
