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%
Let's assume the cost price be (CP) = x
So selling price (SP) = 112.5x
Price marked on good ( MP ) = 300
According to question MP - 25% = SP
? x = 200, hence the cost price be Rs. 200.
Cost price (CP) = 10 / 12 ,
Selling price (SP) = 12 / 10
Profit (%) = [ (SP - CP) / CP ] x 100
? Profit (%) = [( 12 / 10 - 10 / 12 ) / (10 / 12) ] X 100 = 44 %
Let the cost price of one gram be Rs. 1, then the mark up price be Rs. 1.2 per g.
Now he sells 1000 g which seems to be 1250 g so he charges to a customer 1250 X 1.2 = Rs. 1500 for 1000 g (or Rs. 1000)
Thus his profit % 1500 -1000 / 1000 X 100 = 50 %
The best way is to go through option. Consider option (a)
Total profit = 15000 x ( 2 / 3 ) x 5 %
= 15000 x ( 2 / 3 ) x ( 5 / 100) = 500
Total loss = 15000 x ( 1 / 3 ) x 2 %
= 5000 x ( 1 / 3 ) x ( 2 / 100) = 100
Net gain = ( 500 - 100 ) = Rs. 400
Hence: option (a) is correct.
Alternatively : [( 1.05 X 2x/3 + 0.98 x/3) - x] = 400
? x=15000
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
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
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
Let the MP 1 kg tea be Rs. 1,
Then CP of 20 kg with discount = 20 x 0.9 = Rs.18
Also 1 kg tea is free. So the retailer gets tea worth Rs. 21 by paying Rs. 18 only.
profit % = ( goods left / goods sold) x 100
= (21-18 / 18 x 100 = 16.66 %
(Since the retailer earn Rs. 3 on each Rs.18)
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
