Answer 1

Step-by-step explanation:

Less CP = 100

if it was sold at 10% loss it means it was sold at = 90

and he gain 5% more , it means it would be sold at = 105

increase in SP = 105-90 = 15

Given increase = 75

means it's = 75/15 = 5 times

that means our CP will also be 5 times = 100*5 = 500

SP1 = CP*(100-loss%)/100 = 500*90/100 = 450

SP2 = CP*(100+profit%)/100 = 500*105/100 = 525
