The average of 50 numbers is 30. If two numbers, 35 and 40, are discarded, then the average of the remaining numbers is nearly.
Solution
Correct Answer: Option D
The average of 50 numbers is 30
Sum of all the numbers = 30 × 50 = 1500
Sum of 48 numbers = 1500 - (35 + 40)
= 1425
New average = 1425/48 = 29.68
Sum of all the numbers = 30 × 50 = 1500
Sum of 48 numbers = 1500 - (35 + 40)
= 1425
New average = 1425/48 = 29.68
