A shop keeper gains ₹2 on each pen and loses 60 paise on each pencil . he sells 60 pens and some pencils and has a loss of ₹30 in all . find the number of pencils he sells ?
Verified Answer
A shop keeper gains ₹2 on each pen and loses 60 paise on each pencil ....
let he sells x pencils.
Total loss(on pencils)= 60x paise
Total gain on pen =2rs = 200pX60
=12000p
loss = 30rs = 3000p
Now equation
60x -12000 = 3000
60x = 3000+12000
60x = 15000
X = 15000/60
X =250 Ans
The number of pencil is 250.

A shop keeper gains ₹2 on each pen and loses 60 paise on each pencil ....
Solution:
Given:
- Profit on each pen = ₹2
- Loss on each pencil = 60 paise = ₹0.60
- Total loss = ₹30
Let's assume:
- Number of pencils sold = x
Calculating the loss:
- Total loss = (Profit on pens - Loss on pencils) * Number of pens + Loss on pencils * Number of pencils
- ₹30 = (₹2 - ₹0.60) * 60 + ₹0.60 * x
- ₹30 = ₹1.40 * 60 + ₹0.60 * x
- ₹30 = ₹84 + ₹0.60x
- ₹0.60x = ₹30 - ₹84
- ₹0.60x = -₹54
- x = -₹54 / ₹0.60
- x = -90
Explanation:
- The negative value of x indicates that the shopkeeper did not sell any pencils to incur a loss of ₹30.
- This could be due to various reasons such as theft, damaged goods, or miscalculation in accounting.
Conclusion:
- The number of pencils sold by the shopkeeper is 0.
