A) 20% 20% 10%
B) 30% 20%
C) 10% 30% 10%
D) 10% 40%
E) 50%

Let the original price = $100

A) 20% 20% 10%
So, the discounted price = ($100)(0.8)(0.8)(0.9) = $57.60

B) 30% 20%
So, the discounted price = ($100)(0.7)(0.8) = $56.00

C) 10% 30% 10%
So, the discounted price = ($100)(0.9)(0.7)(0.9) = $56.70

D) 10% 40%
So, the discounted price = ($100)(0.9)(0.4) = $54.00

E) 50%
So, the discounted price = ($100)(0.5) = $50.00

Which of the following discount scheme options would be best suited for him if he wants to offer least discount in absolute terms?

Answer: option E

We can let the original price (i.e., the price before any discounts) be 100. Now let’s determine the final discounted price for each of the given options:

A. 100 x 0.8 x 0.8 x 0.9 = 57.6

B. 100 x 0.7 x 0.8 = 56

C. 100 x 0.9 x 0.7 x 0.9 = 56.7

D. 100 x 0.9 x 0.6 = 0.54

E. 100 x 0.5 = 50

We see that option A offers the smallest discount in absolute terms.

Answer: A
