Question

A man sold two clocks for rs 240 each, gaining 20% on one and losing 20% on the other find his gain or loss percent?plz reply soon

Answer 1

cost of first = 240/1.2 = 200
cost of 2nd = 240/.8 = 300

percentage change = (200+300)/480 = 1.04166..

he made a profit of appr 4.17%

Answer 2

cost of first = 240/1.2 = 200
cost of 2nd = 240/.8 = 300
actual c.p= (200+300)/2
= 500/2 = rs 250
s.p < c.p therefor loss
loss = 250 - 240 = 10
loss% = (10/250)* 100 = 4%
