Mr.A sells a bicycle to Mr.B at aprofit of 20 percent and Mr. Bsells it to Mr. C at a profit of 25 percent . If Mr. C pays RS. 1500 . What did Mr. A pay for it​

Answer 1

Let the CP for Mr.B be x

1500 = x+25x/100

1500 = x +x/4

1500 = 4x+x/4

1500= 5x/4

x = 1500×4/5

x = 1200

Let the CP for Mr.A be y

1200 = y +20y/100

1200 = 120y/100

y = 1200×100/120

y = 1000
