Select the option in which the numbers are not related
in the same way as are the number of the following set. (54, 23, 26)Solution
Product of both digits of 1st number + Product of both digits of 2nd number = 3rd number. (54, 23, 26) → (5 × 4) + (2 × 3) = (20 + 6) = 26 (65, 36, 48) → (6 × 5) + (3 × 6) = (30 + 18) = 48 (43, 25, 22) → (4 × 3) + (2 × 5) = (12 + 10) = 22 (68, 44, 64) → (6 × 8) + (4 × 4) = (48 + 16) = 64 (72, 30, 72) → (7 × 2) + (3 × 5) = (14 + 15) = 29.
