Letâs observe the first two sets of numbers (P and Q) carefully, and then try to find the missing number in the 3rd set (R). Letâs take Set P first. Letâs add all the numbers. 2 5 2 3 6 = 18 Now, letâs take Set Q. Again, add all the numbers. 7 4 3 5 2 = 21 Set Q â Set P = 21 â 18 = 3 That means there is a difference of 3 between the total of Set P and Set Q. We can suppose there will be difference of 3 between the total of Set Q and Set R. So, the total of Set R should be Set R â Set Q = 3 Set R â 21 = 3 Or, Set R = 3 21 = 24 Letâs add the numbers in Set R. 7 2 4 8 ? = 24 21 ? = 24 ? = 24 â 21 = 3 Hence, the right answer is Option B.

Logic is - Central numbers are increasing in order .... 2...3...4 In first and second figures... Addition of left and right numbers = Addition of top and bottom numbers Means......... In fig1... 2+6 = 5+3 = 8 In fig2... 7+2 = 4+5 = 9 Therefore.... In fig3... 7+3 = 2+8 = 10 Hence the answer is B
