Question

# A biscuit factory produced $950$ biscuit packets in a day. How many biscuit packets will the factory produce in the three months January, February and March ( There is no holiday during three months)?

Hint: You must know if we produce $x$ number of biscuits per day, then for $n$ days, we will produce $nx$ biscuits. So here, we must know the number of days in January, February and March. You will get your answer.

In this question, it is given that there is a biscuit factory which produces $950$ biscuit packets in a day. So the question is asked to find the total number of biscuits produced in the three months, January, February and March.
So we know if something we produce $x$ items per day and if we do it for $n$ number of days, then our total production will become $nx$.
Similarly, we know the per day production of biscuits by the factory is $950$.
Now we want to know how much it will produce in January, February and March month.
So, let's find out separately for all three months,
Let's say January
So how many days are in January ?
It is obvious and clearly known that January contains $31$ days.
So, if per day production of biscuits is $950$,
Then total biscuits produced in January
$= 950 \times 31 = 29450$
Now for February,
We know it has $28$ days
Total number of biscuits produced in February
$= 950 \times 28 = 26600$
Now for March it is clearly known that it contains $31$ days.
Total number of biscuits produced in March
$= 950 \times 31 = 29450$
So for getting total number of biscuits produced in these three months $=$sum of every month production
$= 29450 + 26600 + 29450 \\ = 85500 \\$
Hence, the total number of biscuits produced by the factory in three months is $85500$.

Note: We must know that January contains $31$ days, February for normal year contains $28$ days and March contains $31$ days. So, total number of days$= 31 + 28 + 31 = 90$ days.
Now total production of biscuits in three months$= 950 \times 90 = 85500$.
