In first case the cost price for each lemons is 25/12 = ₹2.08
In the second case the selling price for each lemon is 12/5 = ₹2.4
That implies gain for each lemon is is selling price -cost price is 2.4-2.08 =₹0.32
Then gain% is (S.P -C.P)/(C.P) * 100 = 0.32/2.08 =0.15385 *100 = 15.385%

A vendor buys lemons at 25rs per dozen and sells them at the Rate of 5for 12rs.find his gain or loss per cent?Solution : cost price of 12 lemons ( in Rupees) = 25 therefore , cost price of one lemon(in Rupees) = 25 / 12 hence cost price of 5 lemons = 5*25/12 =125/12 =10.416 Selling price of 5 lemons (in Rupees) = 12

Since the S.P of 5 lemons is more than C.P. hence the vendor has gain. Therefore , Gain % = S.P - C.P/C.P*100 =12 - 10.416/10.416*100 Gain % = 15.2

Hope this helps you !!!
