Correct Answer - Option 4 : 33.6
Given:
Average of 6 values = 11.2
Each number is multiplied by 3
Formula Used:
Average = Sum of values/number of values
Concept Used:
If each number is multiplied by same factor then average of the whole group containing these numbers is also multiplied by the same factor.
Calculation:
The new average = 3 × old average
⇒ 3 × 11.2
⇒ 33.6
∴ If 3 is multiplied to each number then the new average will be 33.6
