Question

A sells a bicycle to b at a profit of 20 and b sells it to c at a profit of 25

Answer 1

A         B          C

100      120       150

Assume 100 for A and after 20 percent profit it will be 120 and after 25 percent profit we will use 120 x 25/100 = 150.

So profit will be 50 percent.

For details solution also you can ask me.

Thanks!
