In a particular month, a shopkeeper incurs a loss of Rs. 15, by losing 30 paise per pencil. Calculate the number of pencil sold in this month.
Given: A shopkeeper incurs a loss of Rs. 15, by losing 30 paise per pencil.
To find: the number of pencils sold this month.
Solution:
Total loss = Rs. 15 = 1500 paise
Loss on 1 pencil = 30 paise
Now,
Number of pencils sold = $\frac{Total\ loss}{Loss\ on\ 1\ pencil}$
Number of pencils sold = $\frac{1500}{30}$
Number of pencils sold = 50 pencils
So, number of pencils is equal to 50.
