Question

Vasundhara ate $3$ ice cream cups out of $20$ kept in the fridge. What percent did she eat?

Answer 1

Hint: In order to find the percent of ice-cream eaten by Vasundhara, divide the amount of ice cream eaten by her with the total amount of ice cream that was kept in the refrigerator. Then multiply the value obtained with $100$.

Complete answer:
We are given a situation, where Vasundhara ate $3$ ice cream cups out of the $20$cups that were kept in the fridge.
We need to find the Percentage of the ice cream eaten by her.
So, according to the situation, total ice cream kept $ = 20$. ……(1)
She ate $ = 3$. ……..(2)
Since, we know that percentage can be found out by the amount she ate multiplied by 100 then by dividing the total amount.
So, accordingly multiplying equation 1 by 100 and dividing them by equation 2, we get:
$Percentage = \dfrac{{ate}}{{total}} \times 100\% $
$ \Rightarrow Percentage = \dfrac{3}{{20}} \times 100\% $
On solving the above equation, we get:
$ \Rightarrow Percentage = 3 \times 5\% $
$ \Rightarrow Percentage = 15\% $
Therefore, Vasundhara ate $15\% $ of the ice cream that was kept in the fridge.

Note:
In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, $\%$.
Percentages are used widely and in many different areas. For example, discounts in shops, bank interest rates, rates of inflation and many statistics in the media are expressed as percentages. Percentages are important for understanding the financial aspects of everyday life.
