Correct Answer: 21


Solution : In a column of the given table, find the difference between the second and the third numbers and then multiply the resultant number by the first number to obtain the fourth number.

In the first column→(48 – 28) × 3 = 20 × 3 = 60
In the second column→(71 – 65) × 18 = 6 × 18 = 108
Similarly, in the third column→
⇒ (35 – x) × 7 = 98
⇒ (35 – x) = 98 ÷ 7
⇒ (35 – x) = 14
⇒ x = 35 – 14 = 21

So, 21 is the missing number in the given figure. Hence, the first option is correct.
