Question

The average of 50 numbers is 30. If two numbers, 35 and 40 are discarded, then what will be the average (approximate) of the remaining numbers?

• A. 28.32
• B. 28.78
• C. 29.32
• D. 29.69
• E. None of the above

Answer 1

The correct option is C 29.32

Sum of all the terms $=30\times 50=1500$
Sum of all the terms when 35 and 40 are discarded = 1500-(35+40) = 1425
Average $=\frac{1425}{48}=29.69$
