Find Q in the addition.

There is just one letter Q whose value we have to find.

Study the addition in the ones column: from Q +3, we get '1' , that is, a number whose ones digit is 1.

For this to happen, the digit Q should be 8. So the puzzle can be solved as shown below.

$\: \: \: \: \: {3 \: 1 \: 8} \\ + \ \: { \underline{1 \: 8 \: 3}} \\ \: \: \: \: \: { \underline {5 \: 0 \: 1}}$

That is, Q = 8.
