Answer 2

Answer:

Cost of N no of oranges at the rate 4 for Rs 10 = (N/4)×10

Cost of N no of oranges at the rate 5 for Rs 10 = (N/5)×10

Cost of N+N = 2N orànges =10×(N/4+N/5)=9N/2 = 4.5N

Selling price of 2N oranges = 20×(2N/9) = 4.444N

Loss = (9N/2) –(40N/9)= N(81–80)/18 = (1/18)N

Cost 4.5 N , loss = (1/18)N

%of loss = {(N/18)/4.5N}× 100 = 100/81= 1.2345679%
