Answer:
B. 13
Step-by-step explanation:
To determine the maximum number of pens that can be purchased for Rs 200, given that each pen costs Rs 15, we can use simple division.
The cost per pen is Rs 15, and we have Rs 200 available to spend. We can find the maximum number of pens by dividing the total money available by the cost of one pen:
Maximum number of pens
=
Total money
Cost per pen
=
200
15
Maximum number of pens=
Cost per pen
Total money
=
15
200
Performing the division:
200
15
=
13.33
15
200
=13.33
Since we can't purchase a fraction of a pen, we take the integer part of the result. Thus, the maximum number of pens that can be purchased is 13.
Therefore, the correct answer is:
