Question

A sold in article to b at A profit of 2.5 %, B sold the same article to C at a loss of 10%. if C paid 9.90 for it, how much did it cost to A​

Answer 1

Step-by-step explanation:

For C

CP = 9.90

For B

SP= 9.90

Loss= 10 per cent

CP= SP×100/100-Loss

= 9.90×100/100-10

= Rs.11

For A

SP=11

Profit= 2.5 percent

CP= 11×100/100+2.5

= 13.5

So, A paid 13.5
