A trader bought 100 oranges at 5 for N40.00 and 20 for N120.00. Find the profit or loss percent

A.

20% profit

B.

20% loss

C.

25% profit

D.

25% loss

Correct answer is D

Cost price CP of the 100 oranges = 1005 x N40.00

selling price SP of the 100 oranges = 10020 x N120

= N600.00

so, profit or loss per cent

= SPCPCP x 100%

= 600800800 x 100%

= 200800 x 100%

Hence, loss per cent = 25%
