Answer - D.Rs.180
Explanation :
Cost Price = x
Total Profit
= 12x * 20/100 + 8x * 10/100 = 320x/100 = 3.2x
= 20x * 15/100 — (ii) Profit of 15% on 20 notes
Total Profit
3.2x - 3x = 36
0.2x = 36
x = 180
Explanation :
Cost Price = x
Total Profit
= 12x * 20/100 + 8x * 10/100 = 320x/100 = 3.2x
= 20x * 15/100 — (ii) Profit of 15% on 20 notes
Total Profit
3.2x - 3x = 36
0.2x = 36
x = 180

Given MP = 120/100*CP. So, CP = 400.
SP -400 = P (Profit)
(130/100)*SP – 400 = 2P
Solving both equation we get, SP = 4000/7 = 571.4
SP -400 = P (Profit)
(130/100)*SP – 400 = 2P
Solving both equation we get, SP = 4000/7 = 571.4

Total CP of Rice = 30 * 40 = 1200
40% of Total Quantity = 40% of 30 = 12
SP = 12*50 = 600
SP = 1200 * 125/100 = 1500
SP of Remaining Quantity = 1500 – 600 = 900
Remaining Quantity = 18kg
Rice per Kg = 900/18 = Rs. 50
40% of Total Quantity = 40% of 30 = 12
SP = 12*50 = 600
SP = 1200 * 125/100 = 1500
SP of Remaining Quantity = 1500 – 600 = 900
Remaining Quantity = 18kg
Rice per Kg = 900/18 = Rs. 50

C.P = 4*50 = 2000
S.P = 10*50*115 /100 + 30*50*125/100 = 2450
Profit = 2450- 2000 = 450
Profit% = 450/2000 * 100 = 22.5

"use of successive percentage"
Let article cost is 100x...,,
100x -> 120x -> 132x -> (132+16)
Arun. Bala. Catherine Dinesh
The difference between the cost price of Dinesh and cost price of Arun was Rs. 500
So, (132x+16) - 100x = 500
X= 121/8
Bala pay to Arun for the article is
120x => 120* 121/8 => 1815

Let Raman buys ‘X’ apples at rate four for a rupee and ‘X’ apples at three for a rupee.
So, cost price = X/4 + X/3
CP = 6/4 + 6/3 = 3.5
Now SP = (125/100)*3.5 = 4.375
So, cost price = X/4 + X/3
CP = 6/4 + 6/3 = 3.5
Now SP = (125/100)*3.5 = 4.375

Selling price = 2400/6 = 400.
% profit = [(400 – 320)/320]*100 = 25
CP = 320.
Selling price = 2400/6 = 400.
% profit = [(400 – 320)/320]*100 = 25

Let initial income = 100 so his saving is rupees = 20.
Now his income is 116 and he save = 116*25/100 = 29
So % increase in saving = (9/20)*100 = 45
Now his income is 116 and he save = 116*25/100 = 29
So % increase in saving = (9/20)*100 = 45

Let he buys x apples at the rate 4/3 and x apples at the rate of 7/4
so cost price = 4x/3 + 7x/4 = 37x/12
and selling price = (9/5)*2x = 18x/5
% gain = [(37x/12 – 18x/5)/(37x/12)]*100 = 17% (approx)
so cost price = 4x/3 + 7x/4 = 37x/12

Kavya Saxena answered |
Explanation:
Reduction in price = 1/5 = 20%
Increase in Quantity = 25%
25% = 6 Kg.
original amount of Sugar = 6*4 = 24Kg.
Original price of the sugar = 240/24 = Rs. 10 per kg.
Reduction in price = 1/5 = 20%
Increase in Quantity = 25%
25% = 6 Kg.
original amount of Sugar = 6*4 = 24Kg.
Original price of the sugar = 240/24 = Rs. 10 per kg.

5940 = (110/100)*cp1, cp1 = 5400
5940 = (90/100)*cp2, cp2 = 6600
So, CP = 5400 + 6600 = 12000
And selling price = 5940 + 5940 = 11880
% loss = (120/12000)*100 = 1
5940 = (90/100)*cp2, cp2 = 6600
So, CP = 5400 + 6600 = 12000
And selling price = 5940 + 5940 = 11880
% loss = (120/12000)*100 = 1

(80/100)*MP = 30000
MP = 37500, CP = 30000
Profit = (15/100)*37500 =5625
SP = 30000+5625 = 35625 rupee
MP = 37500, CP = 30000
Profit = (15/100)*37500 =5625

Let the total profit = 100
Amount left after donation = 50
Amount left after reinvestment = 20
Now, 5x/8 – 3x/8 = 2400
⇒ 2x/8 = 2400 = 9600
⇒ 1/5 of y = 9600 => y = 48000
Amount left after donation = 50
Amount left after reinvestment = 20
Now, 5x/8 – 3x/8 = 2400
⇒ 2x/8 = 2400 = 9600
⇒ 1/5 of y = 9600 => y = 48000

Ravi Singh answered |
Solution:
Given:
- Rahul's cost price of laptop = Rs.50,000
- Rahul sells laptop to Ravi at a loss of 20%
- Ravi sells laptop to Suresh at a profit of 25%
- Suresh returns laptop to Ravi and recovers Rs.4.50 for every Rs.5 he paid
Calculations:
1. Rahul's selling price to Ravi:
- Rahul's selling price = 80% of Rs.50,000 (20% loss)
- Rahul's selling price = Rs.40,000
2. Ravi's cost price of laptop:
- Ravi's cost price = Rs.40,000
3. Ravi's selling price to Suresh:
- Ravi's selling price = 125% of Rs.40,000 (25% profit)
- Ravi's selling price = Rs.50,000
4. Amount recovered by Suresh after returning laptop:
- Amount recovered = Rs.4.50 for every Rs.5 paid
- Amount recovered = Rs.4.50 / Rs.5 = 90% of the cost price
5. Suresh's cost price of laptop:
- Suresh's cost price = Rs.50,000
6. Suresh's loss:
- Suresh's loss = Rs.50,000 - Rs.45,000 (Amount recovered)
- Suresh's loss = Rs.5,000
Therefore, the amount of Suresh's loss is Rs.5,000. So, the correct answer is option D: Rs.5,000.0.50/5 * 50,000 = 5000
Given:
- Rahul's cost price of laptop = Rs.50,000
- Rahul sells laptop to Ravi at a loss of 20%
- Ravi sells laptop to Suresh at a profit of 25%
- Suresh returns laptop to Ravi and recovers Rs.4.50 for every Rs.5 he paid
Calculations:
1. Rahul's selling price to Ravi:
- Rahul's selling price = 80% of Rs.50,000 (20% loss)
- Rahul's selling price = Rs.40,000
2. Ravi's cost price of laptop:
- Ravi's cost price = Rs.40,000
3. Ravi's selling price to Suresh:
- Ravi's selling price = 125% of Rs.40,000 (25% profit)
- Ravi's selling price = Rs.50,000
4. Amount recovered by Suresh after returning laptop:
- Amount recovered = Rs.4.50 for every Rs.5 paid
- Amount recovered = Rs.4.50 / Rs.5 = 90% of the cost price
5. Suresh's cost price of laptop:
- Suresh's cost price = Rs.50,000
6. Suresh's loss:
- Suresh's loss = Rs.50,000 - Rs.45,000 (Amount recovered)
- Suresh's loss = Rs.5,000
Therefore, the amount of Suresh's loss is Rs.5,000. So, the correct answer is option D: Rs.5,000.0.50/5 * 50,000 = 5000

Explanation:
Profit(Calculated on SP) = 20% of 1800 = 360
Profit(calculated on CP)
x + x/5 = 1800
x = 1500
Profit = 300
Difference = 360 – 300 = 60
Profit(Calculated on SP) = 20% of 1800 = 360
Profit(calculated on CP)
x + x/5 = 1800
x = 1500
Profit = 300
Difference = 360 – 300 = 60

Given:
- Profit Calculation Methods:
- P calculates profit on Selling Price (SP).
- Q calculates profit on Cost Price (CP).
- Profits:
- P's profit: 40% of SP.
- Q's profit: 60% of CP.
- Difference in Profits: ₹1,000.
- Selling Price for both P and Q: Same and denoted as S.
<
Steps to Calculate the Selling Price
- Calculate P's Cost Price (CPP):
- P's profit is 40% of SP.
- ProfitP = 0.40 x S
- CPP = SP - ProfitP = S - 0.40S = 0.60S
- Calculate Q's Cost Price (CPQ):
- Q's profit is 60% of CPQ.
- ProfitQ = 0.60 x CPQ
- Selling Price for Q: SP = CPQ + ProfitQ = CPQ + 0.60CPQ = 1.60CPQ
- Therefore, CPQ = SP / 1.60 = S / 1.60
- ProfitQ = 0.60 x (S / 1.60) = 0.375S
- Set Up the Profit Difference Equation:
- Difference in profits: ProfitP - ProfitQ = ₹1,000
- Substitute the expressions for profits:
- 0.40S - 0.375S = 1,000
- 0.025S = 1,000
- S = 1,000 / 0.025 = 40,000
- Conclusion:
- The selling price for both P and Q is ₹40,000.
Final Answer
The selling price for both P and Q is ₹40,000.

Let's break down the given information and solve the problem step by step.
Given information:
- The TV was purchased for Rs. 54000.
- The price was marked up by 40%.
- It was sold at a discount of 20% on the marked price.
Step 1: Finding the marked price
Since the price was marked up by 40%, we can find the marked price by adding 40% of the purchase price to the purchase price itself.
Marked price = Purchase price + 40% of the purchase price
= Rs. 54000 + 40% of Rs. 54000
= Rs. 54000 + (40/100) * Rs. 54000
= Rs. 54000 + (2/5) * Rs. 54000
= Rs. 54000 + Rs. 21600
= Rs. 75600
So, the marked price of the TV is Rs. 75600.
Step 2: Finding the selling price
Since the TV was sold at a discount of 20% on the marked price, we can find the selling price by deducting 20% of the marked price from the marked price itself.
Selling price = Marked price - 20% of the marked price
= Rs. 75600 - 20% of Rs. 75600
= Rs. 75600 - (20/100) * Rs. 75600
= Rs. 75600 - (1/5) * Rs. 75600
= Rs. 75600 - Rs. 15120
= Rs. 60480
So, the selling price of the TV is Rs. 60480.
Step 3: Finding the profit percentage
Profit percentage can be calculated using the formula:
Profit percentage = (Profit / Cost price) * 100
In this case, the profit is the difference between the selling price and the purchase price, and the cost price is the purchase price.
Profit = Selling price - Purchase price
= Rs. 60480 - Rs. 54000
= Rs. 6480
Profit percentage = (6480 / 54000) * 100
= (12 / 100) * 100
= 12%
Therefore, the profit percentage of the cost price is 12%.
Hence, the correct answer is option D) 12%.
Given information:
- The TV was purchased for Rs. 54000.
- The price was marked up by 40%.
- It was sold at a discount of 20% on the marked price.
Step 1: Finding the marked price
Since the price was marked up by 40%, we can find the marked price by adding 40% of the purchase price to the purchase price itself.
Marked price = Purchase price + 40% of the purchase price
= Rs. 54000 + 40% of Rs. 54000
= Rs. 54000 + (40/100) * Rs. 54000
= Rs. 54000 + (2/5) * Rs. 54000
= Rs. 54000 + Rs. 21600
= Rs. 75600
So, the marked price of the TV is Rs. 75600.
Step 2: Finding the selling price
Since the TV was sold at a discount of 20% on the marked price, we can find the selling price by deducting 20% of the marked price from the marked price itself.
Selling price = Marked price - 20% of the marked price
= Rs. 75600 - 20% of Rs. 75600
= Rs. 75600 - (20/100) * Rs. 75600
= Rs. 75600 - (1/5) * Rs. 75600
= Rs. 75600 - Rs. 15120
= Rs. 60480
So, the selling price of the TV is Rs. 60480.
Step 3: Finding the profit percentage
Profit percentage can be calculated using the formula:
Profit percentage = (Profit / Cost price) * 100
In this case, the profit is the difference between the selling price and the purchase price, and the cost price is the purchase price.
Profit = Selling price - Purchase price
= Rs. 60480 - Rs. 54000
= Rs. 6480
Profit percentage = (6480 / 54000) * 100
= (12 / 100) * 100
= 12%
Therefore, the profit percentage of the cost price is 12%.
Hence, the correct answer is option D) 12%.

Let cost price per kg = C, then
[1260*c*110/100] – [(1260/4)*c*105/100 + (1260/3)*c*108/100 + (525*c)*112/100] = 40.95
U will get C = 3

Quantity of Solution B = 100 litre
Quantity of Solution A = 25 litre
CP of 1 litre Solution B = Rs.10
CP of 1 litre Solution A = Rs.5
CP = 100 * 10 + 25 * 5 = 1125
SP = (100 + 25)*10 = 1250
Profit = 1250 – 1125 = 125
% = 125 * 100 / 1125 = 100/9%
Quantity of Solution A = 25 litre
CP of 1 litre Solution B = Rs.10
CP of 1 litre Solution A = Rs.5
CP = 100 * 10 + 25 * 5 = 1125

Let price of 1 kg rice = Rs.10.
CP of 800 gm rice = Rs.8.
She wants to earn a profit of 40% on per Kg
SP = 10 + 40% of 10 = Rs. 14 per kg.
Faulty balance shows 800 gm = 1000 gm (1 kg)
She sells 800 gm for Rs.14.
Profit = 14 – 8 = Rs. 6.
Profit(%) = 6/8 * 100 = 75%.
CP of 800 gm rice = Rs.8.
She wants to earn a profit of 40% on per Kg
SP = 10 + 40% of 10 = Rs. 14 per kg.
Faulty balance shows 800 gm = 1000 gm (1 kg)
She sells 800 gm for Rs.14.
Profit = 14 – 8 = Rs. 6.
Profit(%) = 6/8 * 100 = 75%.

C.P. of 150 pendrives = 150 x 500 = Rs. 75000
∴ Total C.P. = 75000 + 500 = Rs. 75500
Marked price of 150 pendrive = 150 x 550 = Rs. 82500
Selling price after discount = 82500 x 95 / 100 = Rs. 78375
∴ percentage profit = [(78375 – 75500) / 75500] x 100 = 3.8%
∴ Total C.P. = 75000 + 500 = Rs. 75500
Marked price of 150 pendrive = 150 x 550 = Rs. 82500
Selling price after discount = 82500 x 95 / 100 = Rs. 78375
∴ percentage profit = [(78375 – 75500) / 75500] x 100 = 3.8%
