Correct Answer: 16
Solution : In a column of the given table, multiply the sum of the first and second numbers by 2 to obtain the third number.
In the first column→2 × (9 + 5) = 2 × 14 = 28
In the second column→2 × (4 + 8) = 2 × 12 = 24
Similarly, in the third column→
⇒ 2 × (x + 5) = 42
⇒ x + 5 = 42 ÷ 2
⇒ x + 5 = 21
⇒ x = 21 – 5
⇒ x = 16
So, 16 is the missing number in the given figure. Hence, the fourth option is correct.
