The average marks of a student in 10 papers are 80. If the highest and the lowest scores are not considered, the average is 81. If his highest score is 92, find the lowest.

  1. 55
  2. 60
  3. 62
  4. 64

Answer

The average marks of a student in 10 papers are 80. 

So, total marks = 80 * 10 = 800

Total marks = (Average of 8 subjects)*8 + Highest Marks + Lowest Marks

80 * 10 = (81 * 8) + 92 + x

x = 60

The correct option is B.
