Question
Study the given pattern carefully and select the number
that can replace the question mark (?) in it. First row: 14, 17, 40 Second row: 52, 26, 56 Third row: 48, 34, [?]Solution
Third number = Sum of the digits of the first number X sum of the digits of the second number For First row: 14, 17, 40 Third number = (1 + 4) X (1 + 7) Third number = 5 X 8 Third number = 40. For Second row: 52, 26, 56 Third number = (5 + 2) X (2 + 6) Third number = 7 X 8 Third number = 56. For Third row: 48, 34, [?] Third number = (4 + 8) X (3 + 4) Third number = 12 X 7 Third number = 84.
