The two digit number is 39 .

Step-by-step explanation:

Let x = tens digit

y= unit digit

The tens digit is greater than the units digit.

i.e. x > y

Product of the digits being 27 .

xy = 27

y=\dfrac{27}{x}         (1)

Their difference being 6.

x-y= 6            (2)

Put value of y from (1) in (2) , we get

x-\dfrac{27}{x}=6\\\\\Rightarrow\ x^2-27=6x\\\\\Rightarrow\ x^2-6x-27=0\\\\ \Rightarrow\ x^2+3x-9x-27=0\\\\ (x+3)(x-9)=0\\\\ x=-3\ or\ x=9

x cannot be negative , so x =9

Then,y= \dfrac{27}{9}=3

Hence , the two digit number is 39.
