Gautam scored 51

Ramesh = 82.5
let average of class expect R and G be k

We have average of 21 students as:
(20k + 82.5)/21 = 62
Solving k=1219.5/20 = 60.975

Average of 22 students is one more than average of 21 students except R, i.e
(20k + 82.5 + G)/22 = (20k + G)/21 + 1
Solving this we get G=51
