Best answer
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
