Question

What could be the maximum value of Q in the following equation?

5P9 + 3R7 + 2Q8 = 1114

Answer 1

if P Q and R are whole nos then the question changes
but in case they are real no. the maximum value is infinite

Answer 2

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
