    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.
