Download Solution PDFGiven:
Average of six numbers = 3.52
Average of two numbers = 3.7
Average of the other two = 2.5
Formula used:
Average = Total sum of numbers/Number of numbers
Calculation:
Total sum of six numbers = 3.52 × 6
⇒ 21.12
Total sum of two numbers = 3.7 × 2
⇒ 7.4
The total sum of the other two numbers = 2.5 × 2
⇒ 5
Total sum of remaining two numbers = 21.12 - 7.4 - 5
8.72
Average of remaining two numbers = 8.72/2 = 4.36
∴ The average of the remaining two is 4.36.
