A sells an ariticle to B for Rs. 45,000 losing 10% in the transaction. B sells it to C at a price which would have given a profit of 10% to A. By what per cent does B gain?
Cost price (CP), Selling price (SP), Profit (P)
A sells an ariticle to B for Rs. 45,000 losing 10%
therefore A's CP = $$ 45000 \times \frac{100}{90} = 50000 $$
B sells it to C at profit of 10% to A.
therefore, B's CP = $$ 50000 \times \frac{110}{100} = 55000 $$
B's CP = A's SP = 45000
B's P% = $$ \frac{10000}{45000} \times 100 = \frac{200}{9} $$
