Attempted by 25 students.
Show answer & explanation
Correct answer: C
Step-by-Step Solution
Understand the Formula: The question defines discount as (Marked Price - Selling Price).
Calculate Discounts for Relevant Articles (C, D, and E):
Discount on C = 450 - 425 = 25
Discount on D = 362 - 318 = 44
Discount on E = 435 - 420 = 15
Calculate J1 (Sum of discount on C and D):
J1 = 25 + 44 = 69
Calculate J2 (Difference of discount on D and E):
J2 = 44 - 15 = 29
Calculate Final Value (J1 - J2):
J1 - J2 = 69 - 29 = 40
