Q: Answer-Study the given pattern carefully and select the number that can replace the question mark [?] in it...

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.
