 | Gaurav Datta answered |
Selling price of the car = Rs.54,000
gain 20%
Friend's cost price of the car = Rs. 54000 x 100/120 = Rs.45,000
Now selling price of the car of the first owner Rs.45000
Loss 10%
Cost price of the car = 45000 x 100/90
= Rs.50,000
gain 20%
Friend's cost price of the car = Rs. 54000 x 100/120 = Rs.45,000
Now selling price of the car of the first owner Rs.45000
Loss 10%
Cost price of the car = 45000 x 100/90
= Rs.50,000

 | Milan Chaudhary answered |
Whenever we get this type of question, we should have formula in mind that,
Gain% = (gain/cost) x 100
Cost = 4700 + 800 = Rs. 5500
S.P. = Rs. 5800
Profit = 5800 - 5500 = 300
Gain% = (gain/cost) x 100
Cost = 4700 + 800 = Rs. 5500
S.P. = Rs. 5800
Profit = 5800 - 5500 = 300

Let's denote the cost price of the first TV as CP1, the cost price of the second TV as CP2, and the selling price of the second TV as SP2.
The man makes a profit of 10% on the first TV, so we can write the selling price of the first TV as:
SP1 = CP1 + 10% of CP1
33000 = CP1 + 0.1 * CP1
33000 = 1.1 * CP1
CP1 = 33000 / 1.1
CP1 = 30000
He sells the second TV at a loss of 20%, so we can write the selling price of the second TV as:
SP2 = CP2 - 20% of CP2
SP2 = 0.8 * CP2
Since he neither gains nor loses on the whole, the total cost price equals the total selling price:
CP1 + CP2 = SP1 + SP2
We already know the values of CP1 and SP1, so we can substitute them in the equation:
30000 + CP2 = 33000 + SP2
We also know that SP2 = 0.8 * CP2, so we can substitute that as well:
30000 + CP2 = 33000 + 0.8 * CP2
Now, we can solve for CP2:
0.2 * CP2 = 3000
CP2 = 15000
Now that we have the cost price of the second TV, we can find its selling price using the relation we found earlier:
SP2 = 0.8 * CP2
SP2 = 0.8 * 15000
SP2 = 12000
So the selling price of the second TV set is Rs. 12000.
The man makes a profit of 10% on the first TV, so we can write the selling price of the first TV as:
SP1 = CP1 + 10% of CP1
33000 = CP1 + 0.1 * CP1
33000 = 1.1 * CP1
CP1 = 33000 / 1.1
CP1 = 30000
He sells the second TV at a loss of 20%, so we can write the selling price of the second TV as:
SP2 = CP2 - 20% of CP2
SP2 = 0.8 * CP2
Since he neither gains nor loses on the whole, the total cost price equals the total selling price:
CP1 + CP2 = SP1 + SP2
We already know the values of CP1 and SP1, so we can substitute them in the equation:
30000 + CP2 = 33000 + SP2
We also know that SP2 = 0.8 * CP2, so we can substitute that as well:
30000 + CP2 = 33000 + 0.8 * CP2
Now, we can solve for CP2:
0.2 * CP2 = 3000
CP2 = 15000
Now that we have the cost price of the second TV, we can find its selling price using the relation we found earlier:
SP2 = 0.8 * CP2
SP2 = 0.8 * 15000
SP2 = 12000
So the selling price of the second TV set is Rs. 12000.

| | Ritika Choudhury answered |
R sold the table at 20% profit at Rs. 90. Thus cost price would be given by: CPR X 1.2 = 90
R’s Cost price = Rs. 75.
We also know that E sold it to R at 25% profit. Thus,
E’s Cost price X 1.25 = 75
-> E’s cost price = 60.
R’s Cost price = Rs. 75.
We also know that E sold it to R at 25% profit. Thus,
E’s Cost price X 1.25 = 75
-> E’s cost price = 60.
On selling 17 balls at Rs. 720, there is a loss equal to the cost price of 5 balls. What is the cost price of a ball?
- a)Rs. 43
- b)Rs. 60
- c)Rs. 55
- d)Rs. 34
Correct answer is option 'B'. Can you explain this answer?
a)
Rs. 43
b)
Rs. 60
c)
Rs. 55
d)
Rs. 34
 | Alok Verma answered |
Let the cost price of a ball be Rs. x.
So, the CP of 17 balls is Rs. 17x.
The CP of 5 balls is Rs. 5x.
Since Loss = CP - SP
So, 5x = 17x - 720
On solving, we get
12 x = 720
that is, x = 60
So, the cost price of a ball is Rs. 60.

S.P. at 5% profit = Rs.(110y/100)
= 11y/10
New C.P. of article = 85y/100
= 17/20
S.P. = Rs.(17y/20 * 110/100)
New C.P. of article = Rs. 187/200
According to Question
11y/10 - 187/200 = 33
33y/200 = 33
y = 200
= 11y/10
New C.P. of article = 85y/100
= 17/20
S.P. = Rs.(17y/20 * 110/100)
New C.P. of article = Rs. 187/200
According to Question
11y/10 - 187/200 = 33
33y/200 = 33
y = 200

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.S.P. of x articles = Rs. 20.Profit = Rs. (20 - x).because [(20 - x)/x] x 100 = 25=> 2000 - 100x = 25x=> 125x = 2000 x = 16.

First we find CP.
If SP is Rs. 85 then CP = Rs 100
If SP is Rs. 18,700, then
CP =
= Rs 22,000
Now, if CP is Rs 100, then SP = Rs. 115
Thus, if CP is Rs. 22,000, then
SP =
=Rs 25,300
If SP is Rs. 85 then CP = Rs 100
If SP is Rs. 18,700, then
CP =
= Rs 22,000Now, if CP is Rs 100, then SP = Rs. 115
Thus, if CP is Rs. 22,000, then
SP =

 | Manoj Ghosh answered |
C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
Gain =(80/1600*100) % = 5%

Cost Price of 1 toy = Rs.375/12 = Rs. 31.25
Selling Price of 1 toy = Rs. 33
So, Gain = Rs. (33 - 31.25) = Rs. 1.75
Profit % = [(1.75/31.25) x 100 ]% = 28/5 % = 5.6%

 | Dhruv Mehra answered |
Let the Cost Price of one article = Rs. 1
CP of x articles = Rs. x
CP of 20 articles = 20
Selling price of x articles = 20
Profit = 25% [Given]
⇒ (SP - CP) / CP = 25 / 100 = 1/4 ⇒ (20-x) / x = 1/4
⇒ 80−4x=x
⇒ 5x=80
⇒ x = 80/5 = 16
