Answer 1

Rs. 110

Explanation:

Details provided:

• Profit of Rs 100 by selling 10 pens.
• Selling price of 10 pens is Rs 1200.

Solution:

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

=
`(Total cost of the pens)/(No. of pens)`

=
`Rs (1100)/(10)`

= Rs 110

Hence,

The cost price for each pen the shopkeeper bought is Rs. 110 (Ans)
