Answer 2

Answer:

1)per hundred’

2)profit

3)interest

4)Loss

5)Units

6)Proportional

7)Principal

Step-by-step explanation:

1)Per cent is derived from Latin word ‘per centum’ meaning ‘per hundred’.

2)The difference SP - CP is profit

3)Interest=Amount-Principal

  so, Amount=Principal + interest

4)SP=CP + Loss

   So, CP-SP=Loss

5)Units must be the same to compare two quantities

6)A ratio is called a Proportional ratio when 2 ratios are equal

1/2=2/4

We have,1/2=(1x4)/(2x4)

                  =4/8

                 

        Then,2/4=(2x2)/(4x2)

                     =4/8

We get that 4/8=4/8,which means 1/2=1/2

So, the ratio of 1:2 and 2:4 is 1:2

Here, the ratios are equal

7)The money you borrow is known as Principal
