A retailer bought 20 kg tea at a discount of 10%. Besides 1 kg tea was freely offered to him by the wholesaler at the purchase of 20 kg tea. Now he sells all the at marked price to a customer.What is the profit percentage of retailer?

Assume market price (MP) = Rs. 100
After 20% discount price = 100 - 20% = Rs. 80
After cash discount of 10% price = 80 - 10% = Rs. 72
Price after 10% spend on interior decoration = 72 + 10% = Rs. 79.2

So the cost price (CP) = Rs. 79.2
Selling price after 25 % profit = CP + 25%
= 79.2 + 25% of 79.2
= 1.25 x 79.2
= 99

When initial market price is 100 rupees the selling price is 99.
So for initial market price 8 Lakh the selling price = 8000000 x ( 99 / 100 )
= 7,92,000

It is based on inverse proportion or product constancy concept.
Reduction in price = 25% (1 / 4)
Increase in amount = 33.33% ( 1 / 3 ) = 4 oranges
? Original price of oranges = 16 / 12 = Rs. 1.33

Reduction in price = 20% ( 1 / 5 )
Increase in amount = 25 % (1 / 4) = 6 kg

It means original amount of sugar needed = 6 X 4 =24 kg
? Original price of the sugar = 240 / 24
= Rs. 10 per kg

Go through options C.

After 80% profit on cost price 100 = 100 + 80% = 180
New SP = 180 / 3 = 60
percentage loss = 40% (100 - 60)
Hence, (c) is correct choice.

Amount purchased = 1100 g
Amount sold = 900 g
Profit % = (200 / 900) X 100
= 22 ²/₉%

Initially :
CP = 100
Profit = x
SP = 100 + x
MP = 133.33

After change
CP = 100
Profit = 2x
SP = [7(100 + x)]/6


Now , since (100 + x) 7/6 - 100 = 2x
? x = 20%
CP = 100
Profit = 20
SP = 120
MP = 133.33

so when CP = 300
Selling price = 300 + 20% = 360.

After change
So when CP = 300
Selling price = 300 + 2 x 20% of 300 = 420

So the increased selling price = Rs. 420

Let the CP be Rs. 1 per g
but he weighs 900 g for every 1000 g
? value of goods sold = 900
Now, let the markup be x%
? MP = 1000 + 1000x / 100 = ( 1000 + 10x )
but since MP = SP,
? SP = ( 1000 + 10x )

Hence, profit (%) = [{( 1000 + 10x ) - 900} / 900] x 100 = 20

? x = 8

Thus the markup = 8%

Let markup price be y.
Cost price (CP) = 20 % discount on MP = 0.8y = 800
? y= Rs.1000 MP

SP at Hazratganz = Rs. 800
SP at Bhootnath = 1000 X 0.85 = 850

So, she requires Rs. 50 more to purchase the same calculator at Bhootnath.

Selling price(SP) = 280.
Cost price (CP) = SP - 14²/₇% = 240.

Actual profit (%) = (40 / 240) x 100 = 16.66%

Anna:
CP = 100
SP = 120

Boney:
CP = 120
SP = 132

Chakori:
CP = 132
SP = 120

Mechanic:
CP = 120 + 12 = 132
SP = 143


Loss of Anna = 143 - 20 = 23
% loss of Anna = (23 / 100) x 100 = 23%
