Answer :
Final answer:
The product of all the numbers on the dial of a telephone, when multiplied together (1×9), is 362,880, which is not one of the provided options. Therefore, the correct answer is 'none of those'.
Explanation:
The product of all the numbers on the dial of a telephone requires multiplying each of the digits typically found on a standard telephone dial, which includes the numbers 1 through 9 (0 is usually excluded since it would result in a product of zero). Therefore, you multiply 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 to find the product. This calculation results in 1 × 2 = 2, 2 × 3 = 6, 6 × 4 = 24, 24 × 5 = 120, 120 × 6 = 720, 720 × 7 = 5040, 5040 × 8 = 40,320, and finally 40,320 × 9 = 362,880. Therefore, the correct answer is none of the options provided, meaning the answer is (d) none of those.
