Question

Lakshmi sold two sarees for rupees 1980 each on one she lost 10% while on the other He gain 10% find her gain or loss percent in whole transaction

Answer 1

SP of one Saree = 1980
she gains10% on one
it's cp= 100/(100+gains)×sp
=100/110×1980 = 1800
she loss 10% on other
it's cp =100/90×1980 =2200
total sp= 1980+1980 = 3960
total cp = 1800+2200=4000
loss =cp-sp
= 4000-3960= 40
loss%= 40/4000×100=1%
