Select the option in which the numbers are related in the same way as are the numbers of the following sets.   (63, 7, 16) (68, 4, 21)   (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13-Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

The logic followed here is: Divide the first number with second number and add the quotient to the second number to get the third number.   (63, 7, 16) à 63 ÷ 7 = 9; 9 + 7 = 16 (68, 4, 21) à 68 ÷ 4 = 17; 17 + 4 = 21   (72, 12, 20) à 72 ÷ 12 = 6; 6 + 12 = 18 → Does not follow the pattern   (42, 14, 19) à 42 ÷ 14 = 3; 3 + 14 = 17 → Does not follow the pattern   (85, 17, 22) à 85 ÷ 17 = 5; 5 + 17 = 22 → Follows the pattern (98, 7, 23) à 98 ÷ 7 = 14; 14 + 7 = 21 → Does not follow the pattern   Hence, the correct answer is (C).
