Question

consider a fruit store where an apple is Rs.35 each or 4 for Rs.100. write a program to scan and get results as the correct total price for an entire shopping cart based on the per-unit prices or the volume prices as applicable.

Answer 1

Answer:

Let the cost of an orange =Rsx

And the cost of an apple =Rsy

According to the question,

5x+3y=35

And 2x+4y=28

⇒x+2y=14

By cross-multiplication method, we have

⇒

−42+70

x

=

−35+70

y

=

10−3

⇒

28

x

=

35

y

=

I II III

On taking I and III ratio, we get

⇒

28

x

=

7

1

⇒x=4

On taking II and III ratio, we get

⇒

35

y

=

⇒y=5

Hence, the cost of an orange is Rs. 4 and cost of an apple is Rs. 5
