Question

A sell a computer to B at a profit of 10% and B sell it to C at a profit of 15%.If C pay Rs.35200 for it,at what price did A sell the computer?

Answer 1

Let the price of a computer be 100x.
Therefore, A sells it at a profit of 10% = 100x + 10% of 100x= 110x

Selling Price of A after profit= Cost Price of B.

Now, B sells it at a profit of 15% = 110x + 15% of 110x = 110x + 16.5x= 126.5x

Selling Price of B after profit= Cost Price of C

Therefore,
126.5x= 35200
or, x= 352000/1265= 278.260

100x= 278.260x100= 27826
