in the same way as are the number of the following set. (12, 15, 90)Solution
The logic followed here is as follows: Multiplication of first and second number is divided by 2 to get the third number. In (12, 15, 90) → 12 X 15 = 180; 180 ÷ 2 = 90 In option (a): (6, 18, 54) → 6 X 18 = 107; 108 ÷ 2 = 54 In option (b): (18, 9, 81) → 18 X 9 = 162; 162 ÷ 2 = 81 In option (c): (21, 10, 105) → 21 X 10 = 210; 210 ÷ 2 = 105 In option (d): (17, 12, 100) → 17 X 12 = 204; 204 ÷ 2 = 102.
