The market price of a mobile is \(Rs.8000\), which is \(10 \ \%\) greater than the cost price. If it is sold at a discount of \(2 \ \%\) on the market price, then find the profit percent of the seller?
\(5.6 \ \%\)
\(7.8 \ \%\)
\(6.5 \ \%\)
\(8.2 \ \%\)
Answer: (b) \(7.8 \ \%\)Solution: Given, market price (selling price) = \(Rs.8000\)market price is \(10 \ \%\) greater than the cost price then the actual cost price of the mobile $$ SP = \frac{100 + P \ \%}{100} \times CP $$ $$ 8000 = \frac{100 + 10}{100} \times CP $$ $$ CP = Rs.7272.72 $$ If mobile sold at \(2 \ \%\) discount then $$ SP = \frac{100 - L \ \%}{100} \times CP $$ $$ SP = \frac{98}{100} \times 8000 $$ $$ SP = Rs.7840 $$ profit on cost price, $$ Profit = 7840 - 7272.72 $$ $$ = Rs.567.28 $$ then the profit percent, $$ P \ \% = \frac{567.28}{7272.72} \times 100 $$ $$ = 7.8 \ \% $$
A man purchased a book at \(Rs.400\) and sold it at a profit of \(5 \ \%\). What would have been the increase in the profit percent if it was sold for \(Rs.450\)?
\(7.5 \ \%\)
\(5.5 \ \%\)
\(8.5 \ \%\)
\(4.5 \ \%\)
Answer: (a) \(7.5 \ \%\)Solution: profit amount if book is sold at the profit of \(5 \ \%\), $$ = 400 \times \frac{5}{100} = Rs.20 $$ profit amount if book is sold at \(Rs.450\), $$ = 450 - 400 = Rs.50 $$ Hence, increased profit percent, $$ P \ \% = \frac{50 - 20}{400} \times 100 $$ $$ = 7.5 \ \% $$
A man purchased \(100\) chocolates at the rate of \(Rs.10\) per dozen. If the man sold all the chocolates at the rate of \(Rs.2\) per chocolate, then find the profit percent of the man?
A shopkeeper purchased bananas at the rate of \(Rs.80\) per hundred. If he spends \(10 \ \%\) on the transportation, then what should be the selling price per hundred to earn a profit of \(20 \ \%\)?
A man purchased chocolates at the rate of \(Rs.50\) per hundred. He spends \(20 \ \%\) on the transportation. Find the cost price of the chocolates per hundred after transportation?
