Nanda’s marks are as follows
In Test 1 → T1 38/40
Test 2 → T2 27/30
Test 3 → T3 48/50
For percentage, multiply by 100
T1 = 38/40 x 100 = 95%
T2 = 27/30 x 100 = 90%
T3 = 48/50 x 100 = 96%
Hence, he has scored highest percentage in test 3
∴ He is done well in T3
Overall percentage is the average of the 3 percentages.
i.e (90+95+96)/3 = 281/50 = 93 2/3%
