Answers & Solutions:
1) Answer (A)
Let, the cost price of 1 kg sugar = x
Rahul uses 680 gm weight instead of 1kg. Hence, actual cost price = 0.68x
He incures a loss of 16%. Hence, selling price = 0.86x
Total profit percentage = (0.86x – 0.68x)/(0.68x) x 100
$\Rightarrow$ (0.16/0.68) x 100
$\Rightarrow$ 23.52
Hence, option A is the correct answer.
2) Answer (A)
Ratio of cost price to the selling price = 32 : 37
Let Cost price = $x=32$ and selling price = $y=37$
=> Profit % = $\frac{(y-x)}{x}\times100$
= $\frac{(37-32)}{32}\times100$
= $\frac{500}{32}=15.625\%$
=> Ans – (A)
3) Answer (B)
Let cost price of 1 article = Rs. $x$ and selling price = Rs. $y$
According to ques, => $39y=42x$
=> $\frac{y}{x}=\frac{42}{39}$
Let $x=39$ and $y=42$
Thus, profit % = $\frac{(y-x)}{x}\times100$
= $\frac{(42-39)}{39}\times100$
= $\frac{300}{39}=7.69\%$
=> Ans – (B)
4) Answer (D)
5) Answer (A)
Let cost price of 1 kg of vegetable = Rs. 1000 (1 gm cost Re. 1)
Weight used by A = $1000-(\frac{10}{100}\times1000)=900$ gm
=> Cost price of 1 kg vegetable (900 gm in reality) = Rs. 900
Selling price after 35% profit = $1000+(\frac{35}{100}\times1000)=Rs.$ $1350$
$\therefore$ Profit % = $\frac{(1350-900)}{900}\times100$
= $\frac{450}{9}=50\%$
=> Ans – (A)
6) Answer (D)
Let total articles = 100 and price of all the articles = Rs. 100
Number of articles sold at 50% loss = $\frac{60}{100}\times100=60$
Selling price of these articles = $60-(\frac{50}{100}\times60)$
= $60-30=Rs.$ $30$
Similarly, selling price of (remaining 40) articles sold at 50% profit = $40+(\frac{50}{100}\times40)$
= $40+20=Rs.$ $60$
Thus, net selling price = Rs. 90
$\therefore$ Overall loss % = $\frac{(100-90)}{100}\times100=10\%$
=> Ans – (D)
7) Answer (B)
Let cost price of a shirt = Rs. $x$ and selling price = Rs. $y$
Profit on selling 25 shirts = Rs. $25(y-x)$
According to ques,
=> $25(y-x)=8x$
=> $25y-25x=8x$
=> $25y=8x+25x=33x$
=> $\frac{y}{x}=\frac{33}{25}$
Let $x=25$ and $y=33$
Thus, profit % = $\frac{(y-x)}{x}\times100$
= $\frac{(33-25)}{25}\times100$
= $8\times4=32\%$
=> Ans – (B)
8) Answer (A)
Cost price = Rs. 595
Selling price = Rs. 684.25
=> Profit % = $\frac{(S.P.-C.P.)}{C.P.}\times100$
= $\frac{(684.25-595)}{595}\times100$
= $\frac{8925}{595}=Rs.$ $15\%$
=> Ans – (A)
9) Answer (C)
Cost price = Rs. 8400
Profit % = 26%
=> Selling price = $8400+(\frac{26}{100}\times8400)$
= $8400+2184=Rs.$ $10,584$
=> Ans – (C)
10) Answer (D)
Let cost price of shopkeeper = Rs. 1000/kg => Re. 1/gm
Selling price after 20% profit = $1000+(\frac{20}{100}\times1000)=Rs.$ $1200$
Selling price = Rs. 1200/900gm
=> Profit % = $\frac{(\frac{1200}{900}-1)}{1}\times100$
= $\frac{300}{900}\times100=\frac{100}{3}$
= $33.33\%$
=> Ans – (D)
11) Answer (C)
Cost price of 21 pens = Rs. 20
=> Cost price of 420 pens = Rs. 400
Similarly, Selling price of 420 pens = Rs. 441
$\therefore$ Profit % = $\frac{(441-400)}{400}\times100$
= $\frac{41}{4}=10.25\%$
=> Ans – (C)
12) Answer (A)
Ratio of cost price and selling price of an article = 5 : 3
Let Cost price = $x=5$ and selling price = $y=3$
=> Loss % = $\frac{(x-y)}{x}\times100$
= $\frac{(5-3)}{5}\times100$
= $2\times20=40\%$
=> Ans – (A)
13) Answer (A)
Cost of 1 dozen apples = Rs. 180
=> Cost of 10 dozen apples = $180\times10=Rs.$ $1800$
=> Cost of 1 apple = $\frac{1800}{10\times12}=Rs.$ $15$
Selling price of 1 apple = Rs. 19.5
=> Profit % = $\frac{(19.5-15)}{15}\times100$
= $1.5\times20=30\%$
=> Ans – (A)
14) Answer (D)
Ratio of selling price to the cost price = 21 : 16
Let Cost price = $x=16$ and selling price = $y=21$
=> Profit % = $\frac{(y-x)}{x}\times100$
= $\frac{(21-16)}{16}\times100$
= $\frac{500}{16}=31.25\%$
=> Ans – (D)
15) Answer (A)
Let cost price = Rs. 100
Loss % = 23%
=> Selling price = $100-(\frac{23}{100}\times100)=Rs.$ $77$
$\therefore$ Ratio of its cost price and selling price = $100:77$
=> Ans – (A)
16) Answer (B)
Let cost price of 1 kg rice = Rs. 1000 (1 gm rice cost Re. 1)
=> Cost price of 1 kg rice (850 gm in reality) = Rs. 850
He sells rice on its cost price, => selling price of 1 kg rice = Rs. 1000
$\therefore$ Profit % = $\frac{(1000-850)}{850}\times100$
= $\frac{150}{8.5}=17.647\equiv17.65\%$
=> Ans – (B)
17) Answer (D)
Investment by R = Rs. 165,000 and by S = Rs. 195,000
=> Ratio of profits at the end of year = $165,000:195,000=11:13$
R’s share in the profit = Rs. 11,000
=> Total profit = $\frac{(11+13)}{11}\times11,000$
=> $24\times1000=Rs.$ $24,000$
=> Ans – (D)
18) Answer (C)
Let total number of articles be 100 and price of each article = Re. 1
=> Total cost price of 100 articles = Rs. 100
Number of articles sold at 15% loss = $\frac{80}{100}\times100=80$
Selling price of 80 articles = $80-(\frac{15}{100}\times80)=Rs.$ $68$
=> Number of articles sold at 15% profit = $100-80=20$
Selling price of 20 articles = $20+(\frac{15}{100}\times20)=Rs.$ $23$
Thus, total selling price of 100 articles = Rs. $(68+23)=Rs.$ $91$
$\therefore$ Overall loss % = $\frac{(100-91)}{100}\times100=9\%$
=> Ans – (C)
19) Answer (D)
Let $x$ kg of rice at Rs 54 per kg must be mixed.
Selling price of final mixture = Rs. 48.4/kg at 10% profit
=> Cost price of final mixture = $\frac{48.4}{(100+10)}\times100=Rs.$ $44$
According to ques,
=> $(54\times x)+(30\times40)=44\times(x+30)$
=> $54x+1200=44x+1320$
=> $54x-44x=1320-1200$
=> $10x=120$
=> $x=\frac{120}{10}=12$ kg
=> Ans – (D)
20) Answer (A)
Cost price of 1st laptop = Rs. 42,500
Profit % on selling it = 12%
=> Selling price of 1st laptop = $42,500+(\frac{12}{100}\times42,500)=Rs.$ $47,600$
Cost price of 2nd laptop = Rs. 36,200
Loss % on selling it = 12%
=> Selling price of 2nd laptop = $36,200-(\frac{12}{100}\times36,200)=Rs.$ $31,856$
$\therefore$ Total cost price = Rs. $(42,500+36,200)=Rs.$ $78,700$
Total selling price = Rs. $(47,600+31,856)=Rs.$ $79,456$
=> Profit = Rs. $(79,456-78,700)=Rs.$ $756$
=> Ans – (A)
