Question

A shop keeper gives an offer 'buy one get one free'on the suits marked at Rs.630 each and still makes a profit if 20%. Find the C.P of each
suit

Answer 1

let the original cost price be c each

1.2(2c) - 2c = 630
.4c = 630
c = 1575

check:
cost price of two suits = 2(1575) = 3150
selling price = 1.2(3150) = 3780
profit = 630
