Question

The cost price of 10 article is equal to the selling price of 8 find the profit or loss per cent

Answer 1

Let the cost price of 10 article = 100

and selling price of 8 article = 100

then c.p. of one article = 100÷10 =10

and s.p. of one article = 100÷8 = 12.5

Gain = ₹ 2.5

Gain % = Gain/C.P. × 100

Gain % = 2.5/100 × 100

Gain % = 2.5 %
