Options:
A) Maximize $ Z=0.08x+0.09y $ subject to, $ x+y\le 50,000,x\ge 15000, $
B) Maximize $ Z=0.08x+0.09y $ subject o, $ x+y\le 50,000,x\ge 15000,y\le 20,000 $
C) Maximize $ Z=0.08x+0.09y $ subject to, $ x+y\le 50,000,x\le 15000,y\ge 20,000 $
D) Maximize $ Z=0.08x+0.09y $ subject to, $ x+y\le 50,000,x\le 15000,y\le 20,000 $

Answer:
Correct Answer: A
Solution:
[a] Let shamili invest x in saving certificate and y in PPF.
$ \therefore x+y\le 50000,x\ge 15000andy\ge 20000 $ Total income $ =\frac{8}{100}x+\frac{9}{100}y $
$ \therefore $ Given problem can be formulated as Maximize $ Z=0.08x+0.09y $ Subject to, $ x+y\le 50000,x\ge 15000,y\ge 20000. $
