Question

Which number should be replaced by the question mark?

• A. $45$
• B. $30$
• C. $52$
• D. $18$

Answer 1

Answer: (B)

$30$

$\frac{7\times 4\times 3}{6}=14;\frac{9\times 2\times 6}{6}=18$
$\frac{12\times 2\times 4}{6}=16;\frac{9\times 4\times 5}{6}=30$

Hence the correct answer is option $B$.
