Correct Answer - Option 1 : 4.6
Given:
Average of six numbers = 3.95
Average of two numbers = 3.4
Average of other two = 3.85
Formula:
Average = Total sum of numbers/Number of numbers
Calculation:
Total sum of six numbers = 3.95 × 6 = 23.7
Total sum of two numbers = 3.4 × 2 = 6.8
Total sum of other two numbers = 3.85 × 2 = 7.7
Total sum of remaining two numbers = 23.7 - 6.8 - 7.7 = 9.2
∴ Average of remaining two numbers = 9.2/2 = 4.6
