Analyzing the answer options to calculate the total profit
(A) 15% of 50 is 7.5
(B) 25% of 50 is 12.5
(C) 33 1/3% of 50 is 16.67
(D) 40% of 50 is 20
(E) 75% of 50 is 37.5
Since selling price is the sum of the cost price and the profit, only 40%
gives us a whole number for selling price, making it our answer choice.(Option D)

Bunuel
Profit = Price - Cost
\(\frac{Profit}{Cost}\) = \(\frac{Price - Cost}{Cost}\) = \(\frac{Price - 50}{50}\)
Now lets make the denominator = 100...So multiply both numerator and denominator by 2
\(\frac{2Price - 100}{100}\)
Now you can equal each answer choice easily with equation above.......You need answer that creates even number to be divided by 2
Choices A, B, & E makes the number ending with 5 odd............Eliminate
Choice C is very clear ..........................................................Eliminate
Only one answer left.
Answer D
Check it
2Price - 100 = 40.........2Price = 140......P= 70...Bingo
