Question

Please solve the given Question.

Answer 1

1st Method:

Let the cost price of A = 100.

Given that A sells a computer to B at a profit of 10%.

Then the Cost price of B  = 100 + 10% of 100

                                            = 100 + 10/100 * 100

                                            = 110.



Given that B sells it to C at a profit of 15%.

Cost price of C = 110 + 15% of 110

                          = 110 + 15/100 * 110

                          = 126.5.


Given that cost price of C = 35200.

Now,

126.5 = 35200

1 = 35200/126.5

100 = 35200 * 100/126.5

        = 27826.

Therefore the cost price of A = ~27826.




2nd Method:

115% of 110% of A = 35200

115/100 * 110/100 * A = 35200

253A/200= 35200

253A = 35200 * 200

253A = 7040000

A = 7040000/253

A = ~27826.
