Question

a man sold two pen at rs 99 each he sold one at loss of 10% and the other at gain of 10% find his loss or gain percentage

Answer 1

1st Pen ;
SP = Rs 99
Loss = 10%
CP = 100/100 - 10 * 99 = Rs 110

2nd Pen ;
SP = 99
Gain = 10%
CP = Rs 100/100+10*99 = 90


Total CP of two pens = Rs 110+90 = 200
Total SP of two pens = Rs 99+99 = 198
CP >SP , i.e, loss
Loss = 200 -198 = Rs 2
Loss % = 2/200*100 = 1 %


Loss = 1 %
