Question

A Man sold two gas stove for ₹8400 each.He sold one at a gain of 20% and the other at a loss of 20%.Find his gain or loss % in the whole transaction.

Answer 1

                            =7000

SP =8400 each

CP 1st gas stove(loss)= 8400×100/80

                          = 10500

CP 2nd (profit) =8400×100/120

                         =7000  

total CP    = 10500+7000=   17500

total SP     = 8400+8400 =    16800

LOSS=   17500-16800   =    700

LOSS%=   700/17500*100   = 2%
