Explanation:

As,
5P9 + 3Q7 + 2R8 = 1114 ……… (i)
According to concept of addition
9 + 7 + 8 = 24 ……. (ii)
5 + 3 + 2 = 10 ………. (iii)
From (i), (ii) and (iii)
We can simply say that
2 + P + Q + R = 11 ………. (iv)
Q would be maximum when P and R will be minimum.
So,
P = R = 0
From (iv)
2 + 0 + 0 + Q = 11
=> Q = 11 − 2
=> Q = 9
Hence option (1)
