Two digits number is divided by the product of their digit and the result is 3.now 18 is added to the number the digit will be inter changed. what is the number.  Choose one:	A) 16	B) 18	C) 20	D) 22	E) 24
Let tenth digit of the number is X and Unit digit of that number is Y, Then the number will be (10X +Y).   Now According to question,   (10X +Y)/XY = 3   (10X +Y) = 3XY --------------------------- (1)   And,   10X +Y +18 = 10Y +X   Y -X = 2 ------------------------------------ (2)   Y = 2 +X ------------------------------ (3)   On solving all the equations, we get number is 24.   answer : 24
