Question

Which of the following are multiples of 8 that are greater than 20 and less than 50?

• A. 24, 32, 40 and 45
• B. 20, 32, 40 and 45
• C. 24, 32, 40 and 48
• D. 24, 32, 36 and 48

Answer 1

The correct option is C 24, 32, 40 and 48

The first 10 multiples of 8 are shown in the figure below.

$8\times 1=88\times 2=168\times 3=248\times 4=328\times 5=408\times 6=488\times 7=568\times 8=648\times 9=728\times 10=80$

But, 24, 32, 40, 48 are greater than 20 and less than 50.
$\therefore$The multiples of 8 which are greater than 20 and less than 50 are 24, 32, 40 and 48.
