Krishan bought 2400 bananas at rs 15 a dozen.He sold 1350 of them at rs 4 and the remaining at 5 for rs 8. find his gain or loss percent.

To find the gain or loss percent, we need to calculate the cost price (CP) and the selling price (SP).

1. Calculate the number of dozens bought:
2400 bananas / 12 = 200 dozens

2. Calculate the cost price of 200 dozens:
CP = 200 x Rs 15 = Rs 3000

3. Calculate the selling price of 1350 bananas:
SP1 = 1350 / 12 * Rs 4 = Rs 450

4. Calculate the selling price of the remaining bananas:
Remaining bananas = 2400 - 1350 = 1050
SP2 = 1050 / 5 * Rs 8 = Rs 1680

5. Calculate the total selling price:
Total SP = SP1 + SP2 = Rs 450 + Rs 1680 = Rs 2130

Now, let's calculate the gain or loss percent:
Gain/Loss = SP - CP = Rs 2130 - Rs 3000 = -Rs 870

Loss percent = (Loss / CP) * 100
Loss percent = (-870 / 3000) * 100
Loss percent = -29 (Rounded to the nearest whole number)

Therefore, Krishan incurred a loss of 29%.

To find Krishan's gain or loss percentage, we need to calculate his total cost price (CP) and total selling price (SP).

First, let's find the cost price (CP) for the bananas he bought.

Krishan bought 2400 bananas at Rs 15 per dozen.
So, the cost price of 1 dozen bananas = Rs 15.
To find the cost price of 2400 bananas, we can divide it by 12.
CP = (2400 bananas / 12) * Rs 15 = Rs 3000.

Next, let's calculate the selling price (SP) for the bananas he sold.

He sold 1350 bananas at Rs 4 each. So, the selling price for these bananas = 1350 * Rs 4 = Rs 5400.
The remaining bananas were sold at 5 for Rs 8. So, the number of remaining bananas = 2400 - 1350 = 1050.
The selling price for the remaining bananas = (1050 / 5) * Rs 8 = Rs 1680.

Now, let's calculate the total selling price (SP).
Total SP = Rs 5400 + Rs 1680 = Rs 7080.

To determine his gain or loss, we need to compare the CP and the SP.

If the SP is greater than the CP, then there is a gain.
If the SP is less than the CP, then there is a loss.

Krishan's CP = Rs 3000.
Krishan's SP = Rs 7080.

Krishan's gain = SP - CP = Rs 7080 - Rs 3000 = Rs 4080.

To find the gain or loss percentage, we use the formula:
Gain or Loss Percentage = (Gain / CP) * 100.

Krishan's gain percentage = (4080 / 3000) * 100 = 136%.

Therefore, Krishan has a gain of 136%.

1380

cost = 2400/12*15

revenue = 1350*4 + (2400-1350)/5*8

% gain or loss = ((revenue-cost)/cost - 1)*100
