A company manufactures two types of products A and B. The storage capacity of its go down is 100 units. Total investment amount is 30,000. The cost price of A and B are 400 and 900 respectively. Suppose all the product have sold and per unit profit is 100 and 120 through A and B respectively. If X units of A and Y units of B be produced, then two linear constraints and is profit line are respectively

• A. \[x+y=100;4x+9y=300,100x+120y=c\]
• B. \[x+y\le 100;4x+9y\le 300,x+2y=c\]
• C. \[x+y\le 100;4x+9y\le 300,100x+120y=c\]
• D. \[x+y\le 100;9x+4y\le 300,x+2y=c\]
