Anirudh secures 85%, 70%, 65% and 60% marks in test papers

Anirudh secures 85%, 70%, 65% and 60% marks in test papers with 100, 120, 140 and 160, respectively as maximum marks. The percentage of his aggregate is ?

1. 65²/₃%
2. 68⁶/₁₃%
3. 66¹/₄%
4. 65¹/₃%

Correct Option: B

Marks secured by Anirudh = [(85/100) x 100] + [(70/100) x 120] + [(65/100) x 140] + [(60/100) x 160]
= (85 + 84 + 91 + 96) = 356
∴ Required percentage = [356/(100 + 120 + 140 + 160)] x 100 %
= (356/520) x 100% = 68⁶/₁₃%
