Answer 2

Answer:

10%

Step-by-step explanation:

• SP of 12 oranges=Rs.72

• Therefore, by unitary method, we can find the SP of 1 orange. We have to divide 72 by 12.

• SP of 1 orange=Rs.7212⇒SP of 1 orange=Rs.6

• We are given the percentage of loss as 10%.  

• %Loss=(CP−SP)CP×100...(i)

• Let us substitute the values in the above formula.

        ⇒10=(x−6)x×100  

       Let the cost price (CP) of one orange be x. We know that percentage of loss is given by

%Loss=(CP−SP)CP×100...(i)

Let us substitute the values in the above formula.

⇒10=(x−6)x×100  

⇒10x=100x−600  

⇒600=100x−10x⇒600=90x

∴x = 20/3.

• The CP of 1 orange is 203 . Let us find the CP of 100 oranges by multiplying 203 by 100.

• %Loss =(((2000/3)-600)/(2000/3)) × 100 = 10%.
