Question
Study the given pattern carefully and select the number
that can replace the question mark [?] in it?Solution
The logic followed here is in rows, the sum of all the numbers of first 3 columns are added and then the sum is multiplied by '2' to get the number given in column 4 In row 1 (13, 9, 14, 66) → (13 + 9 + 14) X 2 = 36 X 2 = 72 In row 2 (15, 10, 13, 82) → (15 + 10 + 13) X 2 = 38 X 2 = 76 Similarly, in row 3 (11, ?, 10, 54) →  (11 + ? + 10) X 2 = 54 (21 + ?) = 54 ÷ 2 21 + ? = 27 ? = 27 - 21 ? = 6. So, '6' will replace the question mark in the given pattern.
