Question

The average of 5 consecutive natural numbers is m. If the next three natural numbers are also included, how much more than m will the average of these 8 numbers be?

• A. 2
• B. 1
• C. 1.4
• D. 1.5

Answer 1

The correct option is D 1.5

The average will increase by
$1.5As,\frac{1+2+3+4+5}{5}=3$
$\frac{1+2+3+4+5+6+7+8}{8}=4.5$
$\therefore$ answer is $4.5-3=1.5$
