Four persons A, B, C and D marked four identical articles at Rs. 5000 each. A sold the article at a discount of 60%, B sold the article at two successive discounts of 60% and 20%, C sold the article at two successive discounts of 40% each and D sold the article at a discount of 70%. What was the descending order of selling prices for A, B, C and D?

A
A, C, B, D

B
C, B, A, D

C
D, A, B, C

D
D, B, A, C

Solution

A sold at a discount of 60%.

S.P. for A = 40% of 5000 = 2000

B sold at a discount of 60% and 20%.

Total discount = 60% + 20% - (60 × 20)/100 = 68%

S.P. for B = (100 - 68)% of 5000 = 1600

C sold at a discount of 40% and 40%.

Total discount = 40% + 40% - (40 × 40)/100 = 64%

S.P. for C = (100 - 64)% of 5000 = 1800

D sold at a discount of 70%.

S.P. for D = 30% of 5000 = 1500

S.P. comparison: A > C > B > D
