Question

Find the missing number,if the same rule is followed row-wise or column-wise.

• A. 2
• B. 3
• C. 6
• D. 5

Answer 1

The correct option is B 3

In the first column, we can see that the 4th, i.e the last entry can be calculated using first three entries as $18\times (12÷3)=72$.

This also applies to the 3rd column, where $32\times (16÷4)=128$.

So, the rule is " 4th entry $=$ (1st entry) $\times$ (2nd entry $÷$ 3rd entry) ".

Applying this rule in the 2nd column, we can find the missing number.

Suppose the missing number is X. Then, according to the rule

$24\times (14÷X)=112$.

Solving it we can find $X$.

Thus, $X=(24\times 14)÷112=336÷112=3$.

So, the value of $X$ is $3$.

So, the correct option is B.
