The cost price of 100 pencils equals the selling price of 60 pencils. The gain or loss percentage is
A33 and 1/3%
B66 and 2/3% ✓ Correct
C50%
D45%
Correct answer: (B) 66 and 2/3% — The gain is 66 and 2/3%, so that is the answer.
Explanation
★The gain is 66 and 2/3%, so that is the answer.
★The selling price of 60 pencils equals the cost price of 100 pencils.
★So the selling price of each pencil is 100 by 60 of its cost, that is 5 by 3 of the cost.
★The gain on each pencil is 5 by 3 minus 1, which is 2 by 3 of the cost.
★As a percentage this is 2 by 3, that is about 66.67%.
★So the gain is 66 and 2/3%.
