Question

A retailer lost 8% by selling a camera for Rs.12800. At what price should he sell it in order to gain 8% ?

Answer 1

required answer will be

12800×108/92,

15026.08

Answer 2

SP = 12800
Loss percent is 8
let the CP be x
$\frac{sp}{cp} = \frac{100 - r}{100} \\ \frac{12800}{x} = \frac{100 - 8}{100} \\ \frac{12800}{x} = \frac{92}{100} \\ x = \frac{320000}{23} 13913.04$
to get more 8 percent profit let the CP be 320000/23 ,
so SP is
$\frac{sp}{cp} = \frac{100 + r}{100} \\ \frac{sp}{ \frac{320000}{23} } = \frac{108}{100} \\ sp = \frac{108 \times 320000}{23 \times 100} \\ sp = 15026.08$
