Which item maintains profit in the same percentage on cost every year?
AA ✓ Correct
BB
CC
DD
Correct answer: (A) A
Explanation
Profit percent is sale price minus cost price, divided by cost price, times 100. For item A it works out to 15 percent in every year, for example 30000 on 200000 in 2015 and 25500 on 170000 in 2019, so item A keeps a steady 15 percent profit throughout.
