Answer:
I will assume that P, Q, and R are the middle digits in three three digit numbers.
In this case, start by expanding each of the numbers on the left hand side (LHS) of the equation:
(500 + 10P + 9) + (300 +10R +7) + (200 + 10Q + 8) = 1114
Collecting like terms
1024 + 10(P+Q+R) = 1114
Isolate the variables to the LHS
10(P+Q+R) = 90
P+Q+R = 9
Because you put no conditions on their values, you can maximize Q with:
P=0
Q=9
R=0
