In an examination A obtained 10% more marks than B, B obtained 20% more marks than C & C obtained 32% less marks than D. If A obtained 272 more marks than C, then find the marks obtained by B.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1020.
Explanation:
Let D obtained 100% marks
Marks of C = 68%
Marks of B = 120 × (68)/100 = 81.6%
Marks of A = 81.6 × (110/100) = 89.76%
Difference of marks of A & C = 272
⇒ 89.76% - 68% = 272
⇒ 21.76% = 272
⇒ 81.6% = (272/21.76) × 81.6 = 1020
So, marks of B = 1020
