From the graph, l

Answer :

Formula used.


Loss/profit percent = × 100


(a). If we take point (40,50)


We get


40y = 50x


4y × 10 = 5x × 10


y= × x


(b). If productive cost of jute is Rs. 60


Then x= 60


y = ×60


y = =Rs. 75


(c). By watching graph


We can see that having y =Rs. 125


Where line crosses at point having x = Rs. 100


Cost price will be Rs. 100


(d). For writing Profit %


Let’s take point (40,50)


Where cost price = Rs. 40


Profit = Selling price – Cost price


= 50 – 40 = 10


Loss/profit percent = × 100


Profit % = × 100


=25%


(e). For writing Profit % on selling price


Let’s take point (40,50)


Where cost price = Rs. 40


Profit = Selling price – Cost price


= 50 – 40 = 10


Loss/profit percent on selling price = × 100


Profit % on selling price= × 100


=20%
