Answers
Given : Average marks of a candidate in 6 subjects are 52. His marks in 5 subjects are 60, 48, 36, 55 and 51
To find : Marks in 6th Subject
Solution:
'
Average marks of a candidate in 6 subjects are 52.
Number of subjects = 6
Average Marks = 52
Total Marks in 6 subjects = 6 * 52
= 312
Marks in 5 subjects - 60, 48, 36, 55 and 51
Let say Marks in 6th Subject - N
Total Marks = 60 + 48 + 36 + 55 + 51 + N
= 250 + N
250 + N = 312
=> N = 62
Hence Marks in 6th Subject = 62
