3) 81.8
4) 80.6
5) 79.6
6) 84
7) 81
8) 82
9) 80
10) 82.8

Solution

Difference in physics marks = 87 – 69 = 18
% due to 18 marks = 18/5 = 3.6
Hence new % = 79.4 + 3.6 = 83

Correct Option: 1 Best Solution (8)

%age of marks earlier = 79.4%

Total marks earlier = 79.4*5=397
Additional marks after improvement =87-69=18
Total marks after improvement=397+18=415
% age after improvement = 415/5= 83

%age of marks before improvement = 79.4%
Additional marks after improvement =87-69=18
increase in % age after improvement = 18/5= 3.6.

new %age = 79.4+3.6=83.0
