Anyway, here goes:

"Below is a puzzle containing 4 different letters, which each represent a different number (positive, integer). The "?" can be substituted for any of the numbers to achieve the totals. The total is the sum of all numbers on that row. Submit the each of the numbers."

K + S + ? + ? = 14 **Eqn1**

? + ? + P + N = 48 **Eqn2**

K + P + ? + ? = 27 **Eqn3**

N + ? + N + S = 20 **Eqn4**

So far i have that:

4<N<18

S<12

K<12

P<25

NB: If u know a way to solve it, but don't have time to actually work out the answers, could you hit me up with a method for solving it?

Cheers
