yah, there are more than one solution, Laxi.
K is a two-digit number, if the sum of the tens and unit digits is 3 less than the product of the two digits. What is the value of K?
how about -30 [10(-3) + 0], since 3 is -ve and 0 cannot be -ve or +ve.
sum = -3
product = 0
diff = -3
though it is only an additional one but i am not sure how correct it is?
