Question

Solution of a sells a bicycle to b at a profit of 20% and b sells it to c at a profit of 5%.If c pays rs 3780,what did a pay for it

Answer 1

Let the C.P of A be 100.

Given that A sells a bicycle to B at 20%. Then the cost price of B = 100 + 20% of 100 = 120%.

Given that B sells a bicycle to C at 5%.Then the cost price of C = 120 + 5% of 120 =120 + 6 = 126.

Given The cost price of C = 3780

If 126 = 3780

     1 = 3780/126

    100 = (3780 * 100)/126

           = 3000.

Cost price of A = 3000.
