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

The correct answer is A as
cost price = SPX100/100-loss
=34.80×100/75
=46.40
cost price = SPX100/100-loss
=34.80×100/75
=46.40

Loss is 20% then 9rp is = 80% cost
use unitary method
80 = 9rp
then
1000= 11.25
then 105 = 11.81
use unitary method
80 = 9rp
then
1000= 11.25
then 105 = 11.81

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

Aarav Sharma answered |
Given:
Selling price of first TV set = Rs. 33000
Profit earned on first TV set = 10%
To find: Selling price of the second TV set
Let's assume the cost price of the first TV set = x
Profit earned on the first TV set = 10%
Therefore, selling price of the first TV set = x + 0.1x = 1.1x
Selling price of the first TV set = Rs. 33000
So, 1.1x = 33000
x = 30000
Cost price of the second TV set = y
Loss incurred on the second TV set = 20%
Therefore, selling price of the second TV set = y - 0.2y = 0.8y
Now, let's assume that the man sells the second TV set at a selling price of z.
Total selling price of both the TV sets = 33000 + z
Total cost price of both the TV sets = 30000 + y
It is given that the man neither gains nor loses on the whole, i.e., total selling price = total cost price
33000 + z = 30000 + y + 0.8y
33000 + z = 38000 + 0.8y
z = 38000 - 0.8y
Substituting the value of z in the above equation, we get:
33000 + 38000 - 0.8y = 30000 + y
71000 - 0.8y = 30000 + y
71000 = 1.8y
y = 71000/1.8
y = 39444.44
Selling price of the second TV set = 0.8y = 0.8 x 39444.44 = Rs. 31555.56
Therefore, option (c) Rs. 27,000 is incorrect and the correct answer is option (a) Rs. 15,000.
Selling price of first TV set = Rs. 33000
Profit earned on first TV set = 10%
To find: Selling price of the second TV set
Let's assume the cost price of the first TV set = x
Profit earned on the first TV set = 10%
Therefore, selling price of the first TV set = x + 0.1x = 1.1x
Selling price of the first TV set = Rs. 33000
So, 1.1x = 33000
x = 30000
Cost price of the second TV set = y
Loss incurred on the second TV set = 20%
Therefore, selling price of the second TV set = y - 0.2y = 0.8y
Now, let's assume that the man sells the second TV set at a selling price of z.
Total selling price of both the TV sets = 33000 + z
Total cost price of both the TV sets = 30000 + y
It is given that the man neither gains nor loses on the whole, i.e., total selling price = total cost price
33000 + z = 30000 + y + 0.8y
33000 + z = 38000 + 0.8y
z = 38000 - 0.8y
Substituting the value of z in the above equation, we get:
33000 + 38000 - 0.8y = 30000 + y
71000 - 0.8y = 30000 + y
71000 = 1.8y
y = 71000/1.8
y = 39444.44
Selling price of the second TV set = 0.8y = 0.8 x 39444.44 = Rs. 31555.56
Therefore, option (c) Rs. 27,000 is incorrect and the correct answer is option (a) Rs. 15,000.

The cost price of 20 dozens of toys = 375*20 i.e per dozen 375= Rs 7500/-the selling price of one dozen toys = 12*33= Rs 396/-the selling price of 20 dozen toys = 396*20= Rs 7920/-gain=sp-cp = 7920-7500 =Rs.420/-gain%=(gain/cp)*100 = 420/7500*100 =5.6%

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.

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.

Given:
Selling price = Cost price + 10% of cost price
Let the cost price be x
Selling price = 1.1x
To find:
Cost price of the article
Solution:
Let the original selling price be y
The cost price of the article if he had bought it at 15% less than what he paid for it = 0.85y
He sold it for Rs. 33 less, so the selling price = y - 33
He gained 10%
Selling price = Cost price + 10% of cost price
1.1x = 1.1(0.85y) + 0.1(0.85y)
1.1x = 0.935y + 0.085y
1.1x = 1.02y
y = 1.078x
Substituting the value of y in the equation y - 33 = 1.1(0.85y)
1.078x - 33 = 0.935y
1.078x - 33 = 0.935(1.078x)
1.078x - 33 = 1.00883x
0.06917x = 33
x = 33/0.06917
x = Rs. 476.86
Therefore, the cost price of the article is Rs. 476.86
But, the options given are not in decimals
So, the closest option to Rs. 476.86 is Rs. 200
Hence, the correct option is (B) Rs. 200.
Selling price = Cost price + 10% of cost price
Let the cost price be x
Selling price = 1.1x
To find:
Cost price of the article
Solution:
Let the original selling price be y
The cost price of the article if he had bought it at 15% less than what he paid for it = 0.85y
He sold it for Rs. 33 less, so the selling price = y - 33
He gained 10%
Selling price = Cost price + 10% of cost price
1.1x = 1.1(0.85y) + 0.1(0.85y)
1.1x = 0.935y + 0.085y
1.1x = 1.02y
y = 1.078x
Substituting the value of y in the equation y - 33 = 1.1(0.85y)
1.078x - 33 = 0.935y
1.078x - 33 = 0.935(1.078x)
1.078x - 33 = 1.00883x
0.06917x = 33
x = 33/0.06917
x = Rs. 476.86
Therefore, the cost price of the article is Rs. 476.86
But, the options given are not in decimals
So, the closest option to Rs. 476.86 is Rs. 200
Hence, the correct option is (B) Rs. 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.

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%

C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.

Gain =(80/1600*100) % = 5%

First we find CP.
If SP is Rs. 85 then CP = Rs 100
If SP is Rs. 18,700, then
CP =

Now, if CP is Rs 100, then SP = Rs. 115
Thus, if CP is Rs. 22,000, then
SP =

If SP is Rs. 85 then CP = Rs 100
If SP is Rs. 18,700, then

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
