Answer: 200.5
As per the question,
30 <= No. of packs of PEN <= 40
80 <= No. of packs of PENCIL <= 110
Total packs per day < 130
Profit per pack of pen = 2.20
Profit per pack of pencil = 1.25
For maximum profit, we should have maximum number of packs of PEN, 40
no. of packs of pencil = 130 - 40 = 90
so, total profit = 40*2.2 + 90*1.25 = 200.5
