 Mohd Irfan said: (Mar 30, 2016) Option D is right, if we multiply a number by 0 we get 0 because in telephone dial one no is always 0. So the answer is zero.

 Nazrana said: (Apr 7, 2016) There are so many numbers in the telephone dial then why we should take only zero?

 Priya said: (Jun 1, 2016) How D is the correct answer explain?

 Nitesh said: (Jun 17, 2016) @Nazrana: Zero comes in last. any no. multiply with zero it will give zero only.

 Srinivas said: (Jul 3, 2016) @Priya. In question, they asked product of all numbers so 0 is one of the numbers if you multiplied anything by 0 you will get 0 always. So none of these .

 Sam said: (Jan 5, 2017) @Priya & @Nazrana As, If we do 1*2*3*4*5*6*7*8*9 = 362880. But when 362880 * 0 gives you 0 only.

 Ravi Raushan said: (Feb 13, 2017) Answer will be zero because in a telephone no. one number must always come 0 and hence product will be zero as any no. on multiplication by zero gives zero as a result.

 Omex said: (Aug 13, 2018) The answer is zero.

 Teirol Marbaniang said: (Jul 3, 2019) I am not understanding this. Please explain to me.

 Larisha said: (Jul 10, 2020) Numbers in the dial of a telephone is: 1 2 3 4 5 6 7 8 9 0. If we multiply all the numbers, the result will be 0 (zero). Because the product of any number multiplied by 0 is 0.
