The total marks obtained by Amit in subjects A, B and C is what percent less than the total marks obtained by Vikram in subjects B, C, D and E?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 40.
The total marks obtained by Amit in subjects A, B and C = .64 × 75 + .65 × 80 + .8 × 100 = 48 + 52 + 80 = 180
The total marks obtained by Vikram in subjects B, C, D and E = .7 × 80 + .73 × 100 + .84 × 50 + .86 × 150 = 56 + 73 + 42 + 129 = 300
Required% = (300 - 180)/300 × 100 = 40%
