Ramesh average marks in the 5 subjects = 52
So, total marks is 52*5 =260
On Reevaluation a paper mark should have 60 instead of 45
Total number in 4 papers except in the paper mistakenly 45 marks evaluated
260-45 = 215
Then, New total marks came to know
After playing 60 on 45
215 + 60 =275
Average of the 5 = 275/5
= 55.
