Amrit bought an article for Rs. 2,200 and sold it for Rs. 2,500. Here, his selling price is greater than the cost price. Hence, he got a profit of Rs. 2,500 - Rs. 2,200 = Rs. 300. If he had sold the article for Rs. 2000, he would have a loss of Rs. 2,200 - Rs. 2,000 = Rs. 200. The price for which an article is bought is known as the cost price (C.P.). The price for which it is sold is known as selling price (S.P.). If the selling price is greater than cost price, there is profit or gain. On the other hand, if the selling price is less than the cost price, there is a loss.
So, Profit = Selling price (S.P) - Cost price (C.P)
P = SP - CP and Loss =Cost price (C.P) -Selling price (S.P)
L = CP - SP
The percentage profit or loss can be calculated using the following formula.
Actual profit = profit% of cost price
\(\text {Profit percentage} = \frac {Profit} {C.P}\times 100\)
Actual loss = loss% of Cost price.
\(\text {Loss percentage} = \frac {Loss} {C.P}\times 100\)
If S.P and profit or loss percent are given then
\(C.P = \frac {S.P \times 100} {100 + P\%} \: {or}\: C.P = \frac {S.P \times 100} {100 - L\%}\)
If C.P. and profit or loss percentage are given then
\(S.P = \frac {C.P \times (100 + P\%)} {100}\: {or}\: S.P = \frac {C.P \times (100 - L\%)} {100}\)
The seller may deduct a certain amount from the price of goods. The deduction is known as discount. The price from which the discount is deducted is called the marked price or labeled price. The price obtained by deducting the discount from marked price is called selling price
i.e. Selling price (S.P) = Market price (M.P) - Discount
S.P = M.P - D
or, M.P = S.P + D
or, D = M.P - S.P
If there is no discount, selling price = marked price [ S.P = M.P ]
\(\text {Discount percentage} = \frac {Discount} {M.P} ×100%\)
Value Added Tax is a tax imposed by the government based on goods and services in each step of production and distribution. VAT is levied in the amount after allowing the discount (if there is) from the market price. In general, VAT is expressed in terms percentage which is called the rate of the VAT and it is fixed by the government. The cost of goods is determined by adding the VAT.
S.P = Orginal cost + VAT
\(\text {Rate of VAT} = \frac {VAT \;Amount} {Cost \; after \; discount (S.P)} \times 100\%\)
VAT amount = Rate of VAT (in%) \(\times\) discounted price.
Solution:
Profit% = 12 %
Profit = Rs 60
Selling price (SP) =?
If profit Rs 12 then SP is Rs 112
If profit Rs 1 then SP is Rs \(\frac{112}{12}\)
If profit Rs 60 then SP is \(\frac{112}{12} \times 60 = Rs \: 560\)
\(\therefore SP\) = Rs 560_{Ans.}
Solution:
Cost price (CP) = Rs 4500
Profit % (P) = 30%
Selling price (SP) =?
\begin{align*} SP &= \left( \frac{100 + P%}{100} \right) \times CP \\ &= \frac{100 + 30}{100} \times 4500 \\ &= \frac{4500 \times 130}{100}\\ &= Rs \: 5850\end{align*}
\(\therefore SP\) = 5850_{Ans.}
Solution:
Cost price (CP) = Rs 3405.50
Gain (G) = Rs 120
Selling price (SP) = ?
We know that,
\begin{align*} SP &= CP + profit \\ &= Rs 3405.0 + Rs 120 \\ &= Rs 3525.50_{ANS.} \end{align*}
Solution:
Cost price (CP) = Rs 220,000 + Rs 83500 = Rs 303,500
Selling price (SP) = Rs 300,000
Loss% =?
\begin{align*} Loss\% &= \frac {CP -SP} {CP} \times 100\% \\ &= \frac{303,500 - 300,000}{303500} \times 100\% \\ &= 1.15\% \end{align*}
\(\therefore \) Loss = 1.15%_{Ans.}
Solution:
Selling price (SP) = Rs 2700
Loss% = 10%
\begin{align*} Cost \: price (CP) &= \frac{SP \times 100}{100 - L\%} \\ &= \frac {2700 \times 100}{100 - 10 }\\ &= \frac{270000}{90} \\ &= Rs \: 3000 \end{align*}
Again,
CP = Rs 3000
Profit % = 7.5%
SP = ?
\begin{align*} SP &= \frac{1100 + P\%}{100 } \times CP \\ &= \frac{100 + 7.5\times 3000}{100}\\ &= Rs \: 3225 \end{align*}
\( \therefore \) selling price = 3325_{Ans}
Solution:
The price of doll before discount = Rs 180
The price of doll after discount = Rs 160
Amount of discount = Rs 180 - Rs 160 = Rs 20
\begin{align*} Discount \% &= \frac{Amount \: of \: discount }{Initial \: price} \times 100\% \\ &= \frac{20}{180} \times 100\% \\ &= 11.11\% _{Ans.} \end{align*}
Solution:
Selling price (SP) = Rs. 164
Loss = 18%
\begin{align*} Cost \: price (C.P.) &= \frac{S.P. \times 100}{100 - Loss \%} \\ &= \frac{164 \times 100}{100 - 18}\\ &= \frac{16400}{82}\\ &= Rs. 200 _{Ans}\end{align*}
Solution:
Market price (MP) = Rs. 1000
Discount % = 10%
\begin{align*}Payment\: amount &= MP - discount\% of MP \\ &= Rs. \: 1000 - \frac{10}{100}\times 1000\\ &= Rs. 1000 - Rs. 100 \\ &= Rs. 900_{Ans} \end{align*}
Solution:
Marked price (MP) = Rs. 150
Selling price after discount (SP) = Rs. 130
\begin{align*} Discount\% &= \frac{MP - SP}{MP} \times 100\% \\&= \frac {150 - 130}{150} \times 100\% \\ &= 13\frac{1}{3} \% \: \: _{Ans}\end{align*}
Solution:
Marked price (P) = Rs 2700
VAT = 13%
\begin{align*} Selling \: price \: (SP) &= MP + VAT\% of MP\\ &= 2700 + \frac{13}{100} \times 2700 \\ &= 2700 + 351 \\ &= Rs. \: 3051 \: \: \: _{Ans.} \end{align*}
Solution:
Let, cost price of calculator (CP_{1}) = Rs x
Cost price of the watch (CP_{2}) = RS (4000 - x)
\begin{align*} SP \: of \: calculator \: (SP_1) &= CP + profit \\ &= x + x \: of \: 10\% \\ &= x + x \times \frac{10}{100}\\ &= \frac{11x}{10}\end{align*}
\begin{align*}SP \: of\: watch \: (SP_2) &=CP - loss\\ &= (4000 - x) -20\% \: of \: (4000 + x)\\ &= (4000 -x) - \frac{20}{100} \times (4000 - x)\\ &=\frac{32000 - 5x -4000 + x}{5}\\ &= 3200 - \frac{4x}{5} \end{align*}
\begin{align*} Total \: SP &= SP_1 + SP_2 \\ &= \frac{11x}{10} + 3200 - \frac{4x}{5}\\ &= \frac{3x}{10} + 3200 \end{align*}
Total CP = 4000
Profit = 1%
\begin{align*}SP &= CP + Profit\\ or, \frac{3x}{10} + 3200 &= 4000 + 1\% of 4000\\ or, \frac{3x}{10} + 3200 &= 4000 + \frac{1}{100} \times 4000\\ or, \frac{3x}{10} &= 4000 + 40 - 3200\\ x &= 840 \times \frac{10}{3}\\ &= Rs \: 2800 \end{align*}
\begin{align*}\text{CP of watch = Rs} \: 4000 -x \\ &= 4000 - 2800 \\ &= 1200 \end{align*}
\( \therefore \) CP of calculator = Rs 2800
\(\therefore\) CP of watch = Rs 1200_{Ans.}
Solution:
Marked price (MP) = Rs 1350
Selling Price (SP) = Rs 1282.50
\begin{align*} Discount &= MP -SP \\&= 1350 - 1282.50 \\ &= Rs \: 67.50 \end{align*}
\begin{align*} Discount\% &= \frac{Discount}{MP} \times 100\% \\ &= \frac{67.50}{1350} \times 100 \\ &= 5\% \: \: _{Ans.} \end{align*}
Solution:
Selling price (SP) = Rs 29660
VAT % = 10 %
\begin{align*} \text {Amount of VAT} &= 29660 \times \frac{10}{100} \\ &= Rs \: 2966 \end{align*}
Solution:
Let, MP = Rs x,
VAT = 10%
\begin{align*} x + x \: of \: 10\% &= 17050 \\ or, x + x \times \frac{10}{100} &= 17050 \\ or, \frac{10x + x}{10} &= 17050 \\ or, x &= \frac{17050 \times 10}{11} \\ \therefore x &= Rs \: 15500 \end{align*}
\begin{align*} \text{Amount of VAT } &= Rs 17050 - Rs 15500 \\ &= Rs 1550 \: _{Ans.} \end{align*}
Solution:
Let, cost price (CP) = Rs x
VAT = 10%
\begin{align*} x + x \: of \: 10\% &= 650 \\ or, x + x \times \frac{10}{100} &= 650\\ or, \frac{11x}{10} &= 650 \\ or, x &= \frac{650 \times 10}{11}\\ \therefore x &= Rs \: 590.90 \end{align*}
Return money for 1 set = Rs 650 - Rs 590.90 = Rs 59.10
Return money for 5 sets = 5 \(\times\) 59.10 = Rs 295.50
Solution:
Price of TV = Rs 24,000
Amount of discount = Rs 1200
Discount % = ?
\begin{align*} Discount\% &= \frac{Discount \: Amount}{Price \: of \: TV} \times 100\% \\ &= \frac{1200}{24000} \times 100\%\\ &= 5\% \end{align*}
\(\therefore \) Discount = 5%
The marked price of a calculator is Rs 260. What is the sale price of it, If 5% discount is allowed?
Solution:
Marked price (MP) = Rs 260
Discount % = 5%
Selling price (SP) = ?
\begin{align*} SP &=MP - MP \: of \: discount\% \\ &= 260 - 260 \times \frac{5}{100} \\ &= Rs \:260 -13 \\&= Rs \: 247 \end{align*}
\(\therefore \) SP = Rs 247 \(_{Ans}\)
Solution:
Let marked price (MP) = Rs x
The price of the article with VAT = Rs 690
VAT =15%
We know that,
The price of the article with \begin{align*} VAT &= x + x \: of \: 15\% \\ 690 &= x + x \times \frac{15}{100} \\ or, 690 &= \frac{23x}{20}\\ or,x &= \frac{690 \times 20}{23} \\ x &= Rs \: 600 \end{align*}
The price excluding VAT is Rs 600.
Solution:
Marked price (MP) = Rs 80,000
Discount = 5%
\begin{align*}Selling\: price \:(SP) &= MP - MP \: of \: discount\% \\ &= Rs 80000 - 80000 \times \frac{5}{100}\\ &= Rs \: 80,000 - 4000 \\&= Rs \: 76,ooo \: \: _{Ans.} \: \end{align*}
Solution:
The price of computer before VAT = Rs x, VAT = 15%
Cost of computer after adding VAT = Rs 46000
\begin{align*} x + x \: of \: 15 &= Rs \: 46000\\ or, x + x \times \frac{15}{100} &= Rs \: 46000\\ or, \frac{20x + 3x}{20} &= 46000 \\ or, x &= \frac{46000 \times 20}{23}\\ \therefore x &= Rs \: 40,000 \end{align*}
\(\therefore \) The price of exclusive of the VAT = Rs 40,000 \(_{Ans.}\)
