Given that , The average marks obtained by 22 candidates in an examination = 45
The average marks of the first 10 candidates = 55 and The average marks of the last eleven = 40
тИ┤ Marks obtained by eleventh candidate = 22 ├Ч 45 тАУ (10 ├Ч 55 + 11 ├Ч 40)
Marks obtained by eleventh candidate = 990 тАУ (550 + 440)
Marks obtained by eleventh candidate= 990 тАУ 990 = 0
