Question

Find the missing number based on the relationship between the first pair:
4:32::9:___

• A. 81
• B. 243
• C. 729
• D. 369
• E. 27

Answer 1

The correct option is B 243

The first pair is 4:32 which is $2^2:2^5$
So, the second pair should also be of the form $n^2:n^5$
$3^2$ so the required number is $3^5$ = 243
