Correct answer is: \(\text{10%}\)
Explanation:
If the S.P. of 1 chocolate be Re.1, then
S.P. of 18 chocolates = Rs.18
C.P. = 18 + 2 = Rs.20\(\therefore \text{Loss percent =} \Large \frac{2}{20} \times 100\)
= 10%
Cost of 4 fans and 3 blowers is Rs.16,500. Also cost of 2 fans. 2 tables and 2 blowers is Rs.12000. Cost of one table is Rs.1,000. What is the cost of 3 fans and one blower?

Correct Answer is: Rs.8,000
Explanation:
Let C.P. of 1 fan = Rs.x
CP of 1 blower = Rs.y
CP of 1 table = Rs.1000 (given)\(\therefore \Large 4x+3y = 16500\)
\(\Large 2x+2y+2 \times 1000 = 12000\)
=> 2x + 2y = 12000 - 2000 = 10000
=> x + y = 5000
Equation (ii) x 4 - (i),
y = 20000 - 16500 = 3500
=> x = 5000 - 3500 = 1500\(\therefore 3x + y = \Large 3 \times 1500 + 3500\)
= Rs.8000

Correct anser is: 0.225 n
Explanation:
\(\Large \frac{1m}{150}=\frac{0.6n}{400}\)
\(\implies 1m = \Large \frac{0.6}{400} \times 150n = \text{2%}\)
A person bought 864 articles and sold 800 of them for the price he paid for 864 articles. He sold the remaining articles at the same price per article as the other 800. The percentage gain on the entire transaction is

Correct answer is: \(\text{8%}\)
Explanation:
Profit per cent
\(=\Large \frac{864 - 800}{800} \times 100\)
\(=\Large \frac{64}{800} \times 100 = \text{8 %}\)
A vendor sells calculators at the rate of Rs.250 each and earns a commission of 20% on each. He also sells pens at the rate of Rs.50 each and earns a commission of 10% on each. How much amount of commission will he earn in three days if he sells 10 calculators and 5 pens a day?
Nithin ? Aug 10 '2022 at 20:35
Correct answer is: Rs.1,575
Explanation:
Commission on 1 calculator
\(=\Large \frac{250 \times 20}{100} = \text{ Rs 50}\)
Commission on 1 pen
\(=\Large \frac{50 \times 10}{100} = \text{Rs 5}\)
Therefore, Required amount of commission
\(=\text{Rs }\Large 3 \left(10 \times 5 + 5 \times 5\right)\)
= Rs.1575

Correct answer is: Rs. 500
Explanation:
\(\eqalign{ & {\text{Let C}}{\text{.P}}{\text{. be Rs}}{\text{. }}x \cr & {\text{Profit}} = 20\% \cr & {\text{S}}{\text{.P}}{\text{.}} = 120\% {\text{ of Rs}}{\text{. }}x \cr & \,\,\,\,\,\,\,\,\,\,\,\, = {\text{Rs}}{\text{.}}\frac{{6x}}{5} \cr & {\text{New C}}{\text{.P}}{\text{.}} = {\text{Rs}}.\left( {x - 100} \right) \cr & {\text{New S}}{\text{.P}}{\text{.}} = {\text{Rs}}.\left( {\frac{{6x}}{5} - 100} \right) \cr} \)
\(\eqalign{ & {\text{Profit = }} \cr & {\text{Rs}}.\left[ {\left( {\frac{{6x}}{5} - 100} \right) - \left( {x - 100} \right)} \right] \cr & = {\text{Rs}}.\frac{x}{5} \cr & \therefore \frac{x}{5} \times \frac{1}{{\left( {x - 100} \right)}} \times 100 = 25 \cr & \Rightarrow 20x = 25\left( {x - 100} \right) \cr & \Rightarrow 5x = 2500 \cr & \Rightarrow x = 500 \cr} \)
