Question

a book and a geometry box were brought for each rupees 200 the shopkeeper loss 5% on the book and 10% gain on the geometry box find the gain or loss​

Answer 1

Answer:

1. Cost price = Rs 4500; Selling price = Rs 5000

Here selling price is more than cost price, so there is a profit.

Profit = Selling price − Cost price

= 5000 − 4500

= Rs 500

Hence, there is a profit of Rs 500.

2. Cost price = Rs 4100; Selling price = Rs 4090

Here selling price is less than cost price, so there is a loss.

Loss = Cost price − Selling price

= 4100 − 4090

= Rs 10

Hence, there is a loss of Rs 10.

3. Cost price = Rs 700; Selling price = Rs 799

Here selling price is more than cost price, so there is a profit.

Profit = Selling price − Cost price

= 799 − 700

= Rs 99

Hence, there is a profit of Rs 99.

4. Cost price = Rs 1000; Selling price = Rs 920

Here selling price is less than cost price, so there is a loss.

Loss = Cost price − Selling price

= 1000 − 920

= Rs 80

Hence, there is a loss of Rs 80.

The complete table is shown below.

Answer 2

Given total cost of 5 pens and 10 pencil = Rs 30
5 pens + 10 pencils = 30
pens + 2 pencils = 1
also given pen cost 3 more than a pencil
i.e, pen = 3 + pencil.
pen - pencil = 3
pens + 2 pencils = 6
_______________
-3 pencils = -3
pencils = 1
pen - 1 = 3
pen = 4
cost of pencils = 1 cost of pen = 4
