Question

a sum of 640 is distributed among three girls a b c b get 70 more than a c get 80more b​

Answer 1

Answer:

let a=x

b= x + 70

c= x + 150

ATQ

a + b + c = 640

x + x + 70 + x + 150 =640

3x + 220 =640

3x = 640 -220= 420

x = 420/3=140

THEREFORE

a =140

b= 140 + 70 =210

c= 140+150=290
