We have that type A requires 3g of silver and 1g of gold and type B requires 1g of silver and 2g of gold.

Silver is 9g, gold is 8g.

Let type A be x and type B be y. Therefore we have

3x+y93x+y\le9

x+2y8x+2y\le8

x0,y0x\ge0, y\ge0

Type A gives profit 40Rs and type B gives profit 50Rs. Thus

40x+50y=z40x+50y= z (max this profit)

Solving for two inequalities:

3x+y93x+y\le9

x+2y8    x2 and y3x+2y\le8 \implies x\le2 \ and\ y\le3

Thus max profit would be: 402+503=23040\cdot2+50\cdot3=230


Answer: 230
