The cost price of 8 books is equal to the selling price of 6 books. Find the gain or loss per cent.

Ashis purchases eggs at the rate of Rs 90 for 150 eggs and sells them at Rs 85 per hundred. Find his gain or loss per cent.

Pls pls help***

No

I'd be happy to help you with these questions! Let's solve them step by step:

1. Finding the gain or loss percentage:
Let's assume the cost price of each book is 'x' and the selling price is 'y'.
According to the question, the cost price of 8 books is equal to the selling price of 6 books. So, we can write the equation:
8x = 6y

To find the gain or loss percentage, we need to know the difference between the selling price and the cost price. We can find this by subtracting the cost price from the selling price:
Gain/Loss = Selling Price - Cost Price

Now, let's calculate the gain or loss percentage using the formula:
Gain or Loss Percentage = (Gain or Loss / Cost Price) * 100

2. Finding the gain or loss percentage in the second question:
Ashis purchases eggs at the rate of Rs 90 for 150 eggs. So, the cost price of each egg is 90/150 = Rs 0.60.
He sells the eggs at Rs 85 per hundred, which means he sells 100 eggs for Rs 85. So, the selling price of each egg is 85/100 = Rs 0.85.

We can now calculate the gain or loss percentage using the formula mentioned above.

Let's solve these two questions step by step.

let r be the rate of increase

8(1) = 6(1+r)
8 = 6 + 6r
6r = 2
r = 1/3 or 33 1/3%

purchase price = 90/150 = .6 per egg
selling price = 85/100 = .85 per egg

percentage gain = .25/.6 = .41666... or 41 2/3%

Mam, I have a question where is .25 come from in 2nd question?
