Question

A men brought pencils at the rate of 6 for 4 and sold them at the rate of 4 for 6 what is his gain percent in the transaction

Answer 1

cost price = cost of one pencil × total no of pencil which is brought

cp = 6×4 = 24

selling price = cost of one pencil ×total pencil which is to be sell

sp = 4×6 = 24

gain in the transaction = sp -cp
= 24 - 24
= 0

% gain in the transaction = (sp - cp)/cp×100
= 0/24×100
= 0
