Question 10: Ram has two laptops and he bought both the laptops at the same price. He incurred a loss of 11 percent by selling one laptop at Rs. 21360. At what price, he should sell the other laptop so that he can make a 7% profit in the entire transaction?

a) Rs. 30,000

b) Rs. 36,400

c) Rs. 30,630

d) Rs. 28,980

Marked price = Rs. 3600

Discount % = 10%

=> Selling price = $3600-(\frac{10}{100}\times3600)$

= $3600-360=Rs.$ $3240$

Profit % = 8%

=> Cost price = $\frac{3240}{(100+8)}\times100$

= $30\times100=Rs.$ $3,000$

=> Ans – (A)

Let selling price = Rs. $100$

=> Profit on selling price = $\frac{20}{100}\times100=Rs.$ $20$

Thus, cost price = $100-20=Rs.$ $80$

$\therefore$ Profit on cost price = $\frac{20}{80}\times100$

= $\frac{100}{4}=25\%$

=> Ans – (D)

Let cost price of shopkeeper = Rs. 1000/kg => Re. 1/gm

Selling price = Rs. 1000/960gm

=> Profit % = $\frac{(\frac{1000}{960}-1)}{1}\times100$

= $\frac{40}{960}\times100=\frac{100}{24}$

= $4\frac{1}{6}\%$

=> Ans – (A)

Cost price of each article = Rs. 4000

Profit % on one article = 12.5%

=> Selling price of first article = $4000+(\frac{12.5}{100}\times4000)$

= $4000+500=Rs.$ $4500$

Similarly, selling price of second article = $4000-(\frac{20}{100}\times4000)$

= $4000-800=Rs.$ $3200$

Thus, total cost price = $4000+4000=Rs.$ $8000$

Total selling price = $4500+3200=Rs.$ $7700$

$\therefore$ Overall loss % = $\frac{(8000-7700)}{8000}\times100$

= $\frac{300}{80}=3.75\%$

=> Ans – (B)

Let cost price of 1 article is x

Selling price of 318 articles = 212 Rs

Cost price of 318 articles = 318 Rs

Profit% = {(318 – 212) / 318} x 100 = (106/318) x 100

$\Rightarrow$ (5300/159) = $33\frac{1}{3}$

Hence, option B is the correct answer.

Cost price of 1 banana = Rs. $\frac{1}{4}$

Profit % = $33\frac{1}{3}=\frac{100}{3}\%$

=> Selling price = $\frac{1}{4}+(\frac{100}{3\times100}\times\frac{1}{4})$

= $\frac{1}{4}+\frac{1}{12}=Rs.$ $\frac{1}{3}$

$\therefore$ Number of bananas that must be sold for a rupee = $\frac{1}{\frac{1}{3}}=3$

=> Ans – (A)

Let Marked price = Rs. 100

Discount % = 20%

=> Mohan’s cost price = $100-(\frac{20}{100}\times100)=Rs.$ $80$

Profit % = 40%

=> Selling price = $80+(\frac{40}{100}\times80)$

= $80+32=Rs.$ $112$

$\therefore$ Percentage of profit on the labelled price = $\frac{(112-100)}{100}\times100=12\%$

=> Ans – (D)

Let us assume the cost price of one-litre milk = Rs. p
Hence cost price of 1 litre water = Rs. 0.25p
Let us assume that Amit used 14-liter pure milk. Hence he must have mixed 3-litre water.
Total cost incurred to Amit = 14*p + 3*0.25p = Rs. 14.75p
The measurement instrument shows 1000 ml reading for every 850 ml.
Hence 17 liter milk must be showing volume as = $\frac{1000}{850}\times 17$ = 20 liters
Total amount of money generated by selling milk = 20*p = Rs. 20p

Profit made by Amit in the transaction = 20p – 14.75p = Rs. 5.25p
Profit percentage = $\frac{5.25}{14.75}\times 100 \approx 35.59$ percent
Hence option A is the correct answer.

Let us assume that he bought 100 kg of apple at Rs. 1 per Kg
Total CP = Rs. 100
Profit required = 20%
SP = Rs. 120
But he has only 70% of the apples left. So, he has to sell 70 apples in Rs.120
SP per apple = Rs.120/70 = Rs.1.71
CP per apple = Rs.1
So, he has to sell at 71% higher than the cost price to make an overall profit of 20%.
Hence, option D is the correct answer.

Hence cost price of the laptop= $\frac{21360}{1 – 0.11}$ = Rs. 24000
SP of both laptops combined = $\frac{107}{100}\times 48000$ = Rs. 51,360
