Question

A Honeybee colony that contains 50,000 bees in a late family has only 10,000 bees at the end of winter. What percentage of the bees lives through the winter season?
A. $80\% $
B. $20\% $
C. $25\% $
D. $50\% $

Answer 1

Hint: In order to find the percent, we will use the formula that the percent of bees live through winter will be equal to the ratio of bees after winter and bees before winter then multiply with 100 to make the percentage.

Complete Step-by-Step solution:
Given the statement “A Honeybee colony that contains 50,000 bees in a late family has only 10,000 bees at the end of winter.”
So, here honey bee colony contains bees before winter =50,000
And because of late fall bees after winter = 10,000
Thus, the percentage of bees live through the winter =
$ = \dfrac{{{\text{remaining bees after the winter }}}}{{{\text{bees before the winter}}}} \times 100$
Substitute the given data in above formula, we have
$
   = \dfrac{{10,000}}{{50,000}} \times 100 \\
   = 20\% \\
$
Hence, $20\% $ of the bees live through the winter season and the correct option is “B”.

Note: In order to solve these types of questions, remember the definition of percentage which states that percentage is a part of a whole expressed in hundredths. Also remember if a decimal fraction in which the denominator of the fraction is a power of 10 i.e 10, 100, 1000 etc. That decimal fraction which has 100 as its denominator is known as percentage.
