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

C.P = 4*50 = 2000
S.P = 10*50*115 /100 + 30*50*125/100 = 2450

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

Sushmita Chaudhary answered |
Cost price of book= 160
selling price of book=136
now, rate of discount = loss % (as discount only leads to some kind of loss)
so CP > SP
so loss = CP - SP = 160-136 = 24
loss % = ( loss / CP ) ÷ 100
=( 24 / 160 ) ÷ 100
= 15 %
So rate of discount = 15%
selling price of book=136
now, rate of discount = loss % (as discount only leads to some kind of loss)
so CP > SP
so loss = CP - SP = 160-136 = 24
loss % = ( loss / CP ) ÷ 100
=( 24 / 160 ) ÷ 100
= 15 %
So rate of discount = 15%

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

Aarav Sharma answered |
Given:
Selling price of an article = Rs. 3740
Loss percentage = 45%
To find:
Cost price of the article
Let the cost price of the article be x.
We know that the selling price of an article is given by:
Selling price = Cost price + Profit or Loss
As Vinod has incurred a loss of 45%, his selling price is only 55% of the cost price.
Hence, we can write:
Selling price = 55% of Cost price
⇒ 3740 = 0.55x
Solving the above equation for x, we get:
x = 6800
Therefore, the cost price of the article is Rs. 6800.
The correct answer is 'Option E' (None of these).

It the SP for both the Items is same and
there is a profit of x% and a loss of x%,
then the resultant loss = x²/100%
So, the resultant loss = 4%.

.: CP of 2 books = 2.80 × 100/96 = 2.92 (Appx);
:. Loss = 2.92 – 2.80 = .12 = 12 paise.

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
and selling price = (9/5)*2x = 18x/5
% gain = [(37x/12 – 18x/5)/(37x/12)]*100 = 17% (approx)

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.

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

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

(S.P of 18 cots) - (C.P of 18 cots) = (C.P. of 3 cots)
C.P. of 21 cots = S.P. of 18 cots = Rs. 16800
Price of 1 cot = 16800/21 = 800rs
C.P. of 21 cots = S.P. of 18 cots = Rs. 16800
Price of 1 cot = 16800/21 = 800rs

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

Loss = 450-300 = 150
Loss percentage = (150/450)*100 =100/3
= 33 1/3 %
Loss percentage = (150/450)*100 =100/3
= 33 1/3 %

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

CP = x
Profit Percentage = x%
SP = x(100 + x)/100
x(100 + x)/100 = 96
x = 60
Profit Percentage = 60%
New SP = 60 * 220 / 100 = 132
Profit Percentage = x%
SP = x(100 + x)/100
x(100 + x)/100 = 96
x = 60
Profit Percentage = 60%
New SP = 60 * 220 / 100 = 132

Marked price = (120/100)*CP
cash sales = 45 and credit sales =15
(120/100)*cp*90/100*45 + (120/100)*cp*95/100*15 – 60*cp = 11400
Cp = 2000
cash sales = 45 and credit sales =15
(120/100)*cp*90/100*45 + (120/100)*cp*95/100*15 – 60*cp = 11400
Cp = 2000

According to question , we have
C.P. of 3 articles = S.P. of 5 articles
Loss = S.P. - C.P. = 5 - 3 = $ 2
Loss% = 2 × 20 = 40%
Second method to solve this question:
Here, p = 3, q = 5
Loss% = 40%
C.P. of 3 articles = S.P. of 5 articles
Loss = S.P. - C.P. = 5 - 3 = $ 2
Loss% = 2 × 20 = 40%
Second method to solve this question:
Here, p = 3, q = 5
Loss% = 40%

1/3rd at 12% loss = 900/3 =300*88/100 =264
900*18/100 = 108 => 600+162+36 = 798
198/600 *100 = 33%
900*18/100 = 108 => 600+162+36 = 798
198/600 *100 = 33%

Cost of A is CP,
cost for B = (80/100)*cp + 1500
selling price of B = 42000 = (105/100)*[(80/100)*cp + 1500] cp = 48125
cost for B = (80/100)*cp + 1500
selling price of B = 42000 = (105/100)*[(80/100)*cp + 1500] cp = 48125

Let Initial Quantity of Solution = 100 litre
After mixing 10% water, Quantity of the mixture = 110 * 110 / 100 = 121 litre
CP of One litre of Solution = Rs.1
Total CP = Rs.100
Total SP = Rs.121
Profit = 121 – 100 = 21
Profit % = 21 * 100/100 = 21%
After mixing 10% water, Quantity of the mixture = 110 * 110 / 100 = 121 litre
CP of One litre of Solution = Rs.1
Total CP = Rs.100
Total SP = Rs.121
Profit = 121 – 100 = 21
Profit % = 21 * 100/100 = 21%
