Question

a shopkeeper sold 2 pair of of jeans for rupees 720 each,gaining 20 % on one and losing 20% and other find the loss or gain percent

Answer 1

HELLO
CP of Jeans 1 = 720
Profit % = 20 %
20% Means that if CP is 100
Then profit is 100
& SP = 100 + 20 = 120
Therefore , CP = 100/120 * 720 = 600
CP of Jeans 2 = 720
Loss% = 20
SP = 100 -20 = 80
CP = 100/80 * 720 = 900
TOTAL CP = 600 + 900 = 1500
TOTAL SP = 720 + 720 = 1440
1500 > 1440
CP > SP
Therefore Loss
Loss% = loss/CP * 100
= 60/1500 * 100 = 4%
