Formula

Profit%={SP-CP}×100÷CP

Loss%={CP-SP}×100÷CP

As given

A man sold two chairs at Rs. 1,200 each. On one he gained 20% and on the other he lost 20%.

Let us assume that the cost price for the chair which gave 20% profit be x .

S.P = Rs 1200

Profit % = 20%

Putting all the values in the formula

20=(1200−x)×100÷X

20x = 120000 - 100x

100x +20x = 120000

120x = 120000

x = Rs1000

Thus cost price of the first chair is Rs 1500

Let us assume that the cost price for the chair which gave 20% loss be y .

S.P = Rs 1200

Loss % = 20%

Putting all the values in the formula

20=(y−1200)×100÷Y

20y = 100y - 120000

100y - 20y = 120000

80y = 120000

y = Rs1500

Therefore the cost price of the second chair is Rs 1500 .

Total cost price of two chairs = Rs1000 + Rs1500= Rs 2500

Total selling price of two chair = Rs 1200 + Rs 1200= Rs 2400

Loss = C .P - S.P

= 2500 - 2400

= Rs 100

Put in the formula

Loss%=100×100÷2500

Loss%=100000÷2500

Loss % = 4%

Therefore the loss in the whole transaction is 4% .
