Question
Select the set in which the numbers are related in the
same way as are the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.) (84, 12, 33) (60, 25, 40)Solution
The 3rd number is obtained by dividing the 1st number by 4 and adding the 2nd number to the result. (84, 12, 33) → (84 ÷ 4) + 12 = 21 + 12 = 33 (60, 25, 40) → (60 ÷ 4) + 25 = 15 + 25 = 40 Option A (48, 15, 30) → (48 ÷ 4) + 15 = 12 + 15 = 27 ≠ 30 Option B (72, 18, 36) → (72 ÷ 4) + 18 = 18 + 18 = 36 Option C (96, 20, 48) → (96 ÷ 4) + 20 = 24 + 20 = 44 ≠ 48 Option D (108, 13, 42) → (108 ÷ 4) + 13 = 27 + 13 = 40 ≠ 42
