LTI Profit and Loss Quiz 1

Let the number of chips, Coke and soda bought be x, y and z.
Given that x + y + z = 80
x ≥ 25, y ≥ 25, z ≥ 25
⇒ 25 ≤ x, y, z ≤ 30
As the increase in cost per soda by Re.1 and the increase in cost per coke by Rs.4 increases the
overall bill by Rs.136, z + 4y = 136
In order to satisfy the above condition, g must be a multiple of 4. Hence, it has to be 28.
Hence, y is 27 and x is 25.
Hence, Ayush purchased 27 Coke.

In this case always loss
Loss = \frac{2p^{2}s}{100^{2} - p^{2}}
Loss = \frac{2\times 20^{2}\times 400}{100^{2} - 20^{2}} = 33.33

Let CP = 100
MP = 120
SP = \frac{120\times 90}{100} = 108
CP = \frac{13230\times \times 100}{108}
= Rs. 12,250

Let Ashish has Rs x
For simplification, x = LCM (40, 90) = 360
Thus, price of one novel = 360 / 40
= Rs. 9
Similarly, price of one pen = 360 / 90
= Rs. 4
Now, amount left after keeping money for food = Rs. (360 – 20% of 360) = Rs. 288
Price of 36 pens, P = 4 × 36 = Rs. 144
Amount left = Rs. (288 – 144) = Rs. 144
Therefore, No. of books Ashish buys = 144/9
= 16

Let Cost Price = 100
Marked price = 100 \times \frac{100+10}{100} = 110
Selling Price = 110\times \frac{100-10}{100} = 99
Loss = 100 - 99 = 1
Loss % = \frac{Loss}{\text{Cost Price}}\times 100
Loss % = \frac{1}{100}\times 100
= 1%

In this case always loss
Loss % = \frac{p^{2}}{100} where p = loss or profit Percentage on individual items.
Loss % = \frac{30^{100}
= 9 %

Let the C.P. of a bag be Rs. 100.

Marked price = Rs. 130

And S.P. = Rs. 110

Discount % = \frac{MP-SP}{MP}\times 100

= \frac{130-110}{100}\times 100
= 15.384%
Discount % ≈ 15%

Thus, Pranay should allow a discount of approximately 15% to gain 10% profit.

selling price of music system: 10,000
Profit - 2000
Cost Price - Selling Price - Profit
CP = 10000 - 2000
CP = 8000
Profit % = Profit * 100 / Cost Price
2000 * 100 / 8000
25%

cost price of 50 Notebooks = Selling price of 40 notebooks

Profit percentage = Goods left /goods sold * 100 = 10/40 * 100 = 25%

Total cost: 50*10 + 40 *12 = 980
Total Revenue = 90*11 = 990
Profit % = (10/100)*980
= 50/49 %
