Answer:
Answer is 4%
Step-by-step explanation:
SP=Rs.840
gain=20%
gain%=
CP
(SP−CP)
×100
20=
CP
(840−CP)
×100
Solving the above equation, we get,
0.20CP+CP=840
CP=
1.2
840
=Rs.700
loss=20%
loss% =
CP
(CP−SP)
×100
20=
CP
(CP−840)
×100
Solving the above equation, we get,
CP−0.20CP=840
CP=
0.8
840
=Rs.1050
Total−CP=700+1050=1750
Total−SP=840+840=1680
loss=1750−1680=Rs.70
loss%=
CP
loss
×100=
1750
70
×100=4%
