Answer 1

Answer:

8%

Step-by-step explanation:

Cost Price

12

40

=3.33 rupees/banana

Selling Price

10

36

=3.6 rupees/banana

Therefore,

It is 43.2 for 12 bananas

Profit=SellingPrice−CostPrice

=43.2−40=3.2

Therefore,

Profit %=

40

3.2

×100

=8% profit

Hence, this is the answer.

Answer 2

Answer:

Consider the number of bananas bought =12

Here LCM of 3 and 4 is 12

We know that

C.P. of bananas =1/3×12=₹4

S.P. of bananas =1/4×12=₹3

Here

Loss=C.P.–S.P.

Substituting the values

=4–3

=Rs.1

Loss%=[Loss/C.P.×100] %

Substituting the values

=[1/4×100] %

So we get

=100/4 %

=25 %
