Question

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

$28$	$10$	$14$
$68$	$20$	$17$
$45$	$?$	$9$

• A. $15$
• B. $18$
• C. $20$
• D. $25$

Answer 1

Answer: (D)

$25$

28	10	14
68	20	17
45	?	9

Here we are First dividing 1st column numbers with the last column numbers and then Multiplying the resulting number by 5 to get the middle number.

For 1st row,

$\frac{28}{14}$ $\to$ 2 $\to$ ($2\times 5$) $\to$ $10$

For 2nd row,

$\frac{68}{17}$ $\to$ 4 $\to$ ($4\times 5$) $\to$ $20$

Similarey for 3rd row,

$\frac{45}{9}$ $\to$ 5 $\to$ ($5\times 5$) $\to$ $25$

Hence, Option D is correct.
