Question

if 0.1% of a certain amount of money is 20, then 20% of the amount is

Answer 1

In mathematics, a percentage is a number or a ratio that can be expressed as a fraction of 100. If we are to calculate a percentage of a number, divide the number by the whole number and multiply by 100. So a percentage means a part per hundred. The word percent means out of 100. It is represented by the symbol "%".

Percentages have no dimension. That is why it is called a dimensionless number. If we say 50% of a number, then it means 50% of its whole.

Percentages can also be represented in decimal or fractional form, for example, 0.6%, 0.25%, etc. In academics, marks obtained in any subject are calculated as percentages. Like Ram, he has 78% marks in his final exam. \

According to the question:

0.1 -20

20 -?

Then:

$20*20/0.1 = 4000$

Answer 2

Answer: If 0.1% of a certain amount of money is 20, then 20% of the amount is 4000

Step-by-step explanation:

In mathematics, when we use the percentage formula (%) we assume the total amount as 100℅. To determine the percentage we have to divide the ratio by the total amount and then multiply the resultant by 100.

Percentages are fractions with 100 as the denominator. Percentage means out of 100 or per 100. The symbol of percentage is "%".

Percentage = (value/total value)*100

For here we have 0.1% of a certain amount of money is 20

0.1 - 20

We have to figure out 20% of the total amount of money.

Therefore,

20% of the total amount of money: 20×20/0.1

= 4000
