Generalization of a concept

I have a query we have a positive number X when divided by positive integer D gives remainder R. Now we have a factor of D say m when X is divided by m what would be the remainder? one thing i have checked through number trials that it may not be R but we get the constant remainder and it can be det...

@Sumit: I agree that the problem should not be (35^2-1)/K, but rather be 35^2 - 1/k. Please help me derive the answer to the later. I tried to solve it this way: 35^2-1/K ---> ((5x5x7x7xK)-1) /K Now i can see that 5x5x7x7xK is a multiple of K and is therefore always divisible by K. But when you sub...

(x,y) vertices are integers with conditions 1<=x<=3, 1<=y<=3 so over all we get 9 coordinates with arrang...
