Correct Answer - Option 1 : 5

Given:

Average of 15 numbers = 35

Concept used:

Sum of observations = Average × Number of observations

Calculation:

Sum of 15 numbers = 35 × 15

 525

Each number divided by 7

The sum of numbers divided by 7 = 525 ÷ 7

The average of 15 numbers = 525/(15

× 7)

⇒ 5

The required average is 5
