Find the number ABCD such that when multipled by 4 gives DCBA. - GoHired
We need to find a number ABCD such that, 4(ABCD) = DCBA
These problems can be tricky and/or tedious, but this one isn't too bad.
Method 1 ) Forming Equations and Solving them
Start with some inequalities:
1 <= A <= 9 (since ABCD is a four-digit number, A can't be zero)
0 <= B <= 9
0 <= C <= 9
4 <= D <= 9 (D must be at least 4*A which is at least 4)
