Question

plz solve this it's urgent​

Answer 1

Explanation:

SP=Rs840

gain = 20%

gain % = SP--CP/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%
