Question
Study the given pattern carefully and select the number
that can replace the question mark (?) in it. Â First row: 84, 42, 49 Second row: 72, 58, 53 Third row: 105, 96, ? (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)Solution
The logic followed in the given series is: (First term á 3) + (Second term á 2) = Third term First row: 84, 42, 49 (84 á 3) + (42á 2) = 49 28 + 21 = 49 49 = 49 Second row: 72, 58, 53 (72 á 3) + (58 á 2) = 53 24 + 29 = 53 53 = 53 Third row: 105, 96, ? (105 á 3) + (96 á 2) = ? 35 + 48 = ? ? = 83 Hence, the correct answer is (C).
