Emeka bought 50machines at a cost of 1000each.he sold one tenth of the machines at 1500 each and the remainder at 1050each.calculate his total gain or loss

To determine Emeka's total gain or loss, we need to calculate the total cost and total revenue.

The total cost of buying 50 machines at a cost of 1000 each is 50 * 1000 = <<50*1000=50000>>50000.

Emeka sold one-tenth of the machines, which is 1/10 * 50 = <<1/10*50=5>>5 machines.
He sold these 5 machines at 1500 each, so his revenue from these sales is 5 * 1500 = <<5*1500=7500>>7500.

The remainder of the machines is 50 - 5 = <<50-5=45>>45 machines.
Emeka sold these 45 machines at 1050 each, so his revenue from these sales is 45 * 1050 = <<45*1050=47250>>47250.

His total revenue is 7500 + 47250 = <<7500+47250=54750>>54750.
To calculate the gain or loss, we subtract the total cost from the total revenue.
Gain/Loss = Total Revenue - Total Cost
Gain/Loss = 54750 - 50000 = <<54750-50000=4750>>4750.

Emeka's total gain is 4750.

A man bought a house for 80,000,000 and sold it for 92,000,000.what percentage profit did he make

To determine the percentage profit, we need to calculate the difference between the selling price and the buying price, and then divide it by the buying price. Finally, we multiply this value by 100 to obtain the percentage.

Profit = Selling Price - Buying Price
Profit = 92,000,000 - 80,000,000 = 12,000,000

Percentage Profit = (Profit / Buying Price) * 100
Percentage Profit = (12,000,000 / 80,000,000) * 100
Percentage Profit = 0.15 * 100
Percentage Profit = 15%

The man made a 15% profit.

Ayo sold a shirt for 7500 and made a gain of 25percent.How much did he buy the shirt

To determine the cost price of the shirt, we need to calculate the original price before the gain was added.

Let's assume the cost price of the shirt is x.

The gain percentage is given as 25%, which means Ayo sold the shirt for 100% + 25% = 125% of its cost price.

This can be written as:

125% of x = 7500

To solve for x, we need to convert 125% to its decimal form, which is 1.25:

1.25x = 7500

Dividing both sides of the equation by 1.25 gives us:

x = 7500 / 1.25

x = 6000

Therefore, Ayo bought the shirt for 6000 Naira.

To calculate Emeka's total gain or loss, we need to determine the cost and profit for each batch of machines sold.

Emeka bought 50 machines at a cost of 1000 each, so the total cost is 50 * 1000 = 50000 Naira.

Emeka sold one-tenth of the machines, which is 50 / 10 = 5 machines, at a selling price of 1500 each. So, the revenue from this batch is 5 * 1500 = 7500 Naira.

For the remaining machines, Emeka sold 45 machines (50 - 5) at a selling price of 1050 each. So, the revenue from this batch is 45 * 1050 = 47250 Naira.

To calculate the gain or loss, we subtract the total cost from the total revenue:

Total revenue = 7500 + 47250 = 54750 Naira
Total cost = 50000 Naira

Gain or loss = Total revenue - Total cost
= 54750 - 50000
= 4750 Naira

Therefore, Emeka has a total gain of 4750 Naira.

To calculate Emeka's total gain or loss, we need to determine the following:

1. The cost of buying 50 machines at $1000 each
2. The revenue generated from selling one tenth of the machines at $1500 each
3. The revenue generated from selling the remaining machines at $1050 each

Let's calculate each of these components:

1. Cost of buying 50 machines at $1000 each:
Total cost = 50 machines × $1000 = $50,000

2. Revenue generated from selling one tenth of the machines at $1500 each:
Number of machines sold = 1/10 × 50 machines = 5 machines
Revenue generated = 5 machines × $1500 = $7500

3. Revenue generated from selling the remaining machines at $1050 each:
Number of machines sold = 50 machines - 5 machines = 45 machines
Revenue generated = 45 machines × $1050 = $47,250

Now, let's calculate the total gain or loss:

Total gain or loss = (Revenue generated - Total cost)
= ($7500 + $47,250) - $50,000
= $54,750 - $50,000
= $4750

Therefore, Emeka has a total gain of $4750.
