Question

if the cost price of 10 envelopes is equal to the selling price of 8 envelopes, find the gain or loss percent

Answer 1

                           SP = 10x
                           CP = 8x

Here,

SP > CP = PROFIT

P = SP - CP
P = 10x - 8x
P = 2x

P% = P/CP×100
P% = 2x/10x×100
P% = 20%
