How? explain ?

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.

There are so many numbers in the telephone dial then why we should take only zero?

@Nazrana: Zero comes in last. any no. multiply with zero it will give zero only.

@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 .

@Priya & @Nazrana

As, If we do 1*2*3*4*5*6*7*8*9 = 362880.
But when 362880 * 0 gives you 0 only.

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.

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.
