उत्तर

Given inequalities: 0 ≤ x ≤ 5, 0 ≤ 2y ≤ 7

Corresponding equality: x  5, y = `7/2`, x = 0 ......(i.e., Y-axis) and y = 0   ......(i.e., X-axis)

Note that 0 ≤ 5 and 0 ≤ `7/2`

∴ Solution set have line x = 5 parallel to Y-axis passing through the point (5, 0), line y = `7/2` parallel to X-axis passing through `(0, 7/2)`, and origin side of both the lines.

Also, x ≥ 0 and y ≥ 0 represent 1st quadrant

The shaded portion represents the graphical solution.

A cooperative society of farmers has 50 hectares of land to grow two crops A and B. The profits from crops A and B per hectare are estimated as Rs 10,500 and Rs 9,000 respectively. To control weeds, a liquid herbicide has to be used for crops A and B at the rate of 20 litres and 10 litres per hectare, respectively. Further not more than 800 litres of herbicide should be used in order to protect fish and wildlife using a pond which collects drainage from this land. Keeping in mind that the protection of fish and other wildlife is more important than earning profit, how much land should be allocated to each crop so as to maximize the total profit? Form an LPP from the above and solve it graphically. Do you agree with the message that the protection of wildlife is utmost necessary to preserve the balance in environment?
