Excluded Based Question 1:
The average of 50 numbers is 38. If two numbers 45 and 55 are excluded, then what will be the average of the remaining numbers ?
Answer (Detailed Solution Below)
Excluded Based Question 1 Detailed Solution
Given:
The average of 50 numbers = 38
Two numbers excluded = 45 and 55
Formula used:
New Average = \(\dfrac{\text{Total Sum of Remaining Numbers}}{\text{Total Remaining Numbers}}\)
Calculation:
Total Sum of 50 numbers = 50 × 38 = 1900
Sum of excluded numbers = 45 + 55 = 100
Total Sum of Remaining Numbers = 1900 - 100 = 1800
Total Remaining Numbers = 50 - 2 = 48
New Average = \(\dfrac{1800}{48}\)
⇒ New Average = 37.5
∴ The correct answer is option (2).
