Question

A machine, on an average, manufactures 2,825 screws a day. How many screws did it produce in the month of January 2006.

Answer 1

Hint: Here we have to apply the formula:
Number of screws produced in ‘n’ days = Number of screws produced in one day $\times $ n
The month of January has always 31 days irrespective of being a leap year.

Complete step-by-step answer:
Here, it is given that a machine manufactures screws. i.e.
The number of screws produced in one day = 2,825
We have to calculate the number of screws produced in the month of January 2006
For that we should know how many days are there in January.
We know that in a year there are 12 months, i.e. for a non-leap year there are 365 days and for a leap year there are 366 days.
 We also know that for a non-leap year the month February has 28 days and in a leap year February has 29 days.
Whether it is a leap year or a non-leap year the month January has 31 days. i.e.
The number of days in the month of January 2006 = 31
Therefore we can say that:
Number of screws produced in January 2006 = Number of screws produced in one day $\times $ Total
                                                                                      number of days in January 2006
Hence January has 31 days in 2006, and screws produced per day is 2,825, we can write:
Number of screws produced in January 2006 $=2825\times 31$
Number of screws produced in January 2006 $=87575$

Therefore, we can say that the number of screws produced in the month of January 2006 is $87575$screws.

Note: Since the year is given don’t get confused regarding leap year. Whether it is leap year or not, January always has 31 days. Here only one day’s average screw manufacturing is given. You have to calculate screw manufacturing for 31 days of January.
