Question

$\begin{array}{ccc}14& 11& \left(75\right)\\ 11& 7& \left(54\right)\\ 9& 8& (....)\end{array}$

• A. 54
• B. 46
• C. 62
• D. 51

Answer 1

Answer: (D)

51

Multiply the sum of numbers from first two columns by 3. The resultant number is the number in third column.
Hence, $3\times (14+11)=75$
$3\times (11+7)=3\times 18=54$
Thus, the missing number is:
$3\times (9+8)=3\times 17=51$
