Loss = Cost price of 5 balls

Loss = 720 - (Selling price of 17 balls)

Loss = Cost price of 17 balls - Selling price of 17 balls

Cost price of 17 balls = Selling price of 17 balls + Loss

= 720 + (Cost price of 5 balls)

Cost price of 1 ball = 60

Explanation

Let the S.P. be Rs. 100

Then C.P will be Rs. 25

Profit will be 75

Profit %=  75/25×100%

=300%

Question: A telephone company charges initially Rs.0.50 and then Rs. 0.11 for every minute. Write an expression that gives the cost of a call that lasts N minutes. (5 marks)

I apple - 2 Rs

8 apples = 2x8

= 16 Rs

Initial charges = Rs 0.5-

Next every min charge = RS0.11 Rs 

No. minutes charges = Nx0.1 =0.11N.R

Total charge = (0.50 +0.11N) Rs

Explanation

To determine the total amount charged by the internet service provider, we need to consider both the one-time setup fee and the monthly service fee for each customer.

1. The one-time setup fee is $100 per customer, so for c customers, the total setup fee is $100c$.
2. The monthly service fee is $50 per customer. For m months, the total service fee per customer is $50m$. Thus, for c customers, the total service fee is 50cm.

Now, we can combine these two components to get the total charge:

$$text{Total Amount} = text{Setup Fee} + text{Service Fee} = 100c + 50cm$$

Explanation

Profit = Selling Price - Cost Price

= 60,000 - 57,000

= 3,000

To find the profit percentage, divide the profit by the cost price and multiply by 100:

Profit Percentage = (Profit ÷ Cost Price) × 100

= (3,000 ÷ 57,000) × 100

= 5.26%

Explanation

Let the first person's investment be x. Then, the second person's investment is x + 1000, and the third person's investment is (x + 1000) + 1000 = x + 2000.

We know that the total investment is Rs. 9000, so we can set up the equation: x + (x + 1000) + (x + 2000) = 9000.

Combine like terms: 3x + 3000 = 9000.

Subtract 3000 from both sides: 3x = 6000.

Divide by 3: x = 2000.

So, the first person invested Rs. 2000, the second person invested Rs. 3000 (2000 + 1000), and the third person invested Rs. 4000 (3000 + 1000).

The profit share of each person is in the ratio of their investments. Let's find the total profit share of the third person: (4000 / 9000) x 5400 = 2400.
