The Total solution for NCERT class 6-12
Findgraphically, the maximum value of z = 2x + 5y, subject to constraints givenbelow:
2x +4y £ 8
3x +y £ 6
X +y £ 4
X ³ 0,y ³ 0
2x + 4y= 8, 3x + y = 6, x + y = 4, x = 0, y = 0.
Theselines are drawn on a suitable scale and the feasible region of the LPP isshaded in the graph.
Fromthe graph we can see the corner points as (0, 2) and (2, 0).
