Question

A shopkeeper allows 15% discount and still makes 5% profit. Find the marked price of an article which costs him Rs. 340

Answer 1

Cost price=Rs340
 5% profit, Selling price= 340 + 5% × 340 = 357
 Marked price = 15% discount = 357 × 100 / 85 = Rs 420

Answer 2

Answer:C.P=340

Gain=5%

S.p=®340*(100+5)/100

=34*150/10=17*21

=357

Now suppose m.p=®100

Discount=15%

Discount=15/100

=®15

:.s.p=®100-®15=®85

If s.p is ®85 then m.p=®100

If s.p is ®1 then m.p =®100/85=20/17

S.p=357 then m.p=®20/17*357

=®20*21=®420
