Answer:
Step-by-step explanation:To solve this problem, let's break down the profit and loss components for each type of item sold by the shopkeeper.
Let:
- Profit earned on each packet of sketch colours = ₹9
- Loss incurred on each packet of pencil colours = ₹4
Now, let's denote:
- Cost price (CP) of a packet of sketch colours = ₹x
- Selling price (SP) of a packet of sketch colours = CP + ₹9
- Cost price (CP) of a packet of pencil colours = ₹y
- Selling price (SP) of a packet of pencil colours = CP - ₹4
To find the values of x and y, we need more information such as the relationship between the cost price and selling price for each type of item.
Answer:
Let's denote:
- The number of packets of sketch colours sold by ( x ).
- The number of packets of pencil colours sold by ( y ).
Given:
- The profit on selling a packet of sketch colours is ₹9.
- The loss on selling a packet of pencil colours is ₹4.
The total profit ( P ) can be calculated using the formula:
[ P = 9x - 4y ]
where:
- ( 9x ) is the total profit from selling ( x ) packets of sketch colours.
- ( 4y ) is the total loss from selling ( y ) packets of pencil colours.
