2) let the integer and equal to 10x+y
according to the question-
10x+y = xy + (x+y)
so, y = 9
and we have taken y as the unit digit so , we can say 9(option 3) is the unit digit of integer N.
3) let the radius of the cylinder equal to R.
and the diameter of the cylinder equal to 2R
given - radius of cone = 5
height of the cone equal to 12.
So , by Thales theorem-
we can say -
r/5 = 12-2r/2r
so, r 30/11( option 3rd )
