Profit and Loss Quiz-1

Let the marked price be Rs. 100
Then, the selling price = Rs. 77
Now , Cost price = \frac{77*100}{63}
= 1100/9
New Selling Price = 77*\frac{125}{100}
Now ,
New Selling Price - Cost Price
= -935/36
(negative indicates loss)
Therefore , loss % = 21.25%

Let us consider the cost price of each smartphone be Rs. x
According to the question,
2(x-9400)=(10600-x)
or, x = 9800

Since , there is 30% concession on the labeled price ,
Therefore, Selling Price = (70 / 100) * Labeled Price
Selling price of Tania = 8750
Let the labeled price be x .
Now, Labeled Price after 25% profit = \frac{125}{100}*\frac{70}{100}x=8750
or, x = 10000

Selling Price = 720 * 15% = Rs. 828
Let the marked price be Rs. x
Therefore, (100 - 10)% of x =  828
or, x = Rs. 920 .

Let the cost price be Rs. 100
Then , the selling price = Rs. 78
Now , Marked Price = (78 / 78 )*100 =Rs. 100
Since the marked price and the cost price is same ,
Therefore ,
Loss % = (100-97)% = 3% .

Let the Cost price be Rs. x and the Selling price be Rs. y
According to the question ,
3(y - x) = (2y - x)
or, y = 2x
Now , profit = (y - x)
= (2x - x)
= Rs. x
Profit % = \frac{x}{x}*100
= 100%

Let the  Cost price be  Rs. 100.
Then, Profit = Rs. 320,
Selling price = Rs. 420.

Now ,
New Cost price = 125% of Rs. 100 = Rs. 125
New Selling price = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295.
[ In the given question , what percentage of the selling price is the profit is asked ]
Therefore , Required Profit % = \frac{295}{420}*100
\simeq 70%

Video solution:

Cost price of 6 items = Re. 1
Selling price of 6 items = 120% of Re 1
= Rs. 6/5

Now ,
For Rs, 6/5 , items sold =6
For Re. 1 . items sold = 6*\frac{5}{6}
= 5 .

Cost Price of ( 26 + 30) kg wheat = Rs.(26*20 + 30*36)
= Rs. 1600
Selling Price o (26 + 30)kg wheat = Rs. (26 + 30)*30
= Rs. 1680
Profit = Rs (1680-1600) = Rs. 80
Therefore , Profit % = 5%

According to the question ,
(Cost price of 17 balls) - (Selling Price of 17 balls) = (Cost Price of 5 balls)

or, (Cost price of 12 balls) = (Selling Price of 17 balls) = Rs.720.
or, Cost Price of 1 ball = Rs. (720 / 12) = Rs. 60
