The cost price of two dozen bananas is Rs.30. After selling 1.5 bananas at the rate of Rs. 12 per dozen, the shopkeeper sells the remaining bananas at the rate of Rs.4 per dozen. What is the loss percentage?

37.5 percent

C.P. of 24 bananas = Rs.32

S.P. of 18 bananas at Rs.12 per dozen = 12 + 6 = Rs. 18

S.P. of remaining 6 bananas at Rs. 4 per dozen = Rs. 2

S.P. of 24 bananas =18 + 2= Rs.20

Loss = 32 − 20 = Rs.12

Loss = \(\frac{12 × 100}{32}\) = 37.5%
