ANSWER

A company produces two types of goods, A and B, that require gold and silver. Each unit of type A requires 3 g of silver and 1 g of gold while that of B requires 1 g of silver and 2 g of gold. The company can use atmost 9 g of silver and 8 g of gold. If each unit of type A brings a profit of ` 40 and that of type B ` 50, find the number of units of each type that the company should produce to maximize the profit. Formulate and solve graphically the LPP and find the maximum profit.

Let the point (x, y) be the current position of helicopter along the curve (y = x2 + 2).

Given jet is placed at the point (3,2).

Therefore, distance between jet and soldier = D

Now, we know that, if D is minimum then D2 is also minimum.

So, D2 =

For minimum D2, we have

⇒ x = 1 as there are no real rots for the equation

Again,

Clearly, for x = 1, distance is minimum.

On putting value of x in the given curve , we get

y = (1)2 + 2 = 3

Therefore, point (1,3) is nearest to point (3,2)

Hence, minimum distance =
