Answer 2

Given:

A pen factory decided to reduce its production by 10% our that of previous month from February.

In January, it produced 3,000 pens.

To find:

How many pens were produced in March.

Solution:

A pen factory decided to reduce its production by 10% our that of previous month from February.

In January, A pen factory produced 3000 pens.  

Number of pens produced in February is 3000 - 10% of 3000

Number of pens produced in February = 3000 - $\frac{10}{100}$ × 3000

Number of pens produced in February = 3000 - 300

Number of pens produced in February = 2700 pens

Number of pens produced in March is 2700 - 10% of 2700

Number of pens produced in March = 2700- $\frac{10}{100}$ × 2700

Number of pens produced in March = 2700 - 270

Number of pens produced in March = 2430 pens

Final answer:

The number of pens produced in March is 2430 pens.
