in order for P/Q to be as big as possible P has to be as big as possible and Q as small as possible....

so lets P=14 (14-5)
q=1 therefor 14 is the max possible value..

whenever you have absolute value, just rewrite the equation twice, witht the second one negative.

For example, the first one is:

p-5=9 and p-5=-9

solve, and you get p = 14 or -4

Same thing works for 2q-7, and q would equal either 6 or 1.

Put them together, and 14 is the biggest number: 14/1

I think the question asked for minimum poss value and not maximum.
Acc to the question , the answer should be -2/3.
Plz confirm the OA or the right question.

q can't be negative, so p has to be negative to make the smallest p/q.
p=-4, q=1. p/q=-4.
