• A. $4$
• B. $8$
• C. $12$
• D. $16$

Answer 1

Answer: (B)

$8$

By multiplying the first three elements of a column, we will get the fourth element

$6\times 5\times 4=120$

$6\times 7\times 3=126$

Let $x$ be the unknown number in the table.

$8\times 5\times x=320$

$\Rightarrow x=\frac{320}{40}$

Hence, $x=8$
