Answer:
Step-by-step explanation:
Given,
No. of pens the shopkeeper has = 10
Selling price of 10 pens = Rs. 1200
Profit made by selling them = Rs 100
So,
Actual price or Cost price of 10 pens
= Rs (1200 - 100)
= Rs 1100
Now,
Cost price for each pen
= [tex]\frac{Total cost of the pens}{No. of pens}[/tex]
= [tex]Rs \frac{1100}{10}[/tex]
= Rs 110
Hence,
The cost price for each pen the shopkeeper bought is Rs. 110 (Ans)
