Let the Cost price of the powerbank = Rs. P
But given that by selling it at Rs. 1950, it gives a loss of 25%
=>
=>
= Rs. 2600
Now, to get a profit of 25%
Selling Price = .
Given
125% ---- 3400
=> 100% ---- ?
=> ? = 3400x100/125 = 2720
=> Cost price of the article = Rs. 2720
Profit when article sold at Rs. 3265 = 3265 - 2720 = 545
Hence, Profit% = Gain x 100/cost price
=> P% = 545 x 100/2720
=> P% = 20%
Let marked price = Rs. 100.
Then, C.P. = RS. 54,
S.P. = Rs. 85
Gain % = 31/64 x 100 = 48.4%.
C.P. of 50 kg wheat = (30 * 11.50 + 20 * 14.25) = Rs. 630.
Let the cost price be x and selling price be y.
Loss = x ? y
When the cost price doubles, the loss gets tripled.
So it becomes like this, 2x ? y = 3(x-y)
=> x = 2y
Loss % = (loss/ C.P) x 100 = [(2y-y)/2y] x 100= 50 %
Let 1kg of Rs. 100 then 840gm is of Rs. 84.
Now (label on can 1kg but contains 840kg ) so for customer it is of Rs. 100 and further gives 4% discount [he sells his article on 4% loss on cost price.]
So now S.P = Rs. 96
But actually it contains 840 gm so C.P for shopkeeper = Rs. 84
S.P = Rs. 96
C.P = Rs. 84
Profit% = {(S.P-C.P)/C.P}x100
{(96-84)/84} x 100 = 14.28571429% PROFIT.
When 3 passengers income was 3x
expense= Rs.30
profit =20% of 30 = Rs.6
That means his earning is Rs.36. so that per passenger fare must be Rs.12.
When 4 passengers
earning = 12x4=Rs.48.
expense =Rs.24.
profit = Rs.24 = 100%
Total cost of all varieties of mangoes = 20 x 2 + 40 x 3 + 50 x 5 = 40 + 120 + 250 = Rs. 410
Then, cost of 1 kg mangoes = 410/10 = Rs. 41
To get 20% profit,
The rate at which the mangoes should be sell = 120/100 x 41 = Rs. 49.2
loss % = %
= (20/10)x(20/10)% = 4%
Let the cost price of a ball is Rs.x
Given, on selling 17 balls at Rs. 720, there is a loss equal to the cost price of 5 balls
The equation is :
17x - 720 = 5x
Solving the equation
we get x = 60
Therefore, cost price of a ball is Rs. 60.
