Question

*6000 for 3 years at 10% per annum. 9. A T.V. is bought for * 42500 and is marked 15% above cost price. Find the gain or loss per cent if 12% discount is allowed on the marked price. D​

Answer 1

Answer:

Given :

Marked price ( MP ) = 20 %

Discount = 15 %

According to the question :

Let the Cost price ( CP ) be ' 100 '

☞ So, MP = 100 + 20

=> Rs. 120.

☞ Discount = 15 % of MP

=> 15 × 120 / 100

=> Rs. 18.

Finding SP :

☞ SP = MP - Discount

=> 120 - 18

=> 102.

Therefore, it's a Gain.

Gain % :

☞ Gain = SP - CP

=> 102 - 100

=> Rs. 2.

☞ Gain Percentage = Gain / CP × 100

=> 2 / 100 × 100

=> 2 %.

Answer 2

$\sf \large \: Solution, \:$

$\sf \: Marked \: price \: is \: 15 \: \% \: above \: the \: cost \: price, \: so \: Marked \: price \: = \: \\ \\ \sf \frac{15}{1 \cancel{00}} \: \times \: 425 \cancel{00} \\ \\ \sf \: 15 + 425 + 42500 \: = \: ₹ \: 42950 \\ \\ \sf \color{red} Marked \: price \:of \: the \: tv \: is \: ₹ \:42950$

$\sf Since \: the \: Marked\:Price\:of \: the \: T.V. \: is \: greater \: than \: the \: Selling\:Price \: its \: a \: profit.$

$\sf \: Profit \: = \: Marked\:Price\:-\:Selling\:Price \\ \\ \sf \: Profit \: = \:42950 \: - \: 42500 \\ \\ \color{aqua}\sf \: Profit \: = \:₹\:450$

$\color{violet} \sf \boxed{Profit \: \% \: = \: \frac{Profit}{Cost \: Price} \: \times \: 100}$

$\sf Profit\: \% \:= \: \frac{450}{425 \cancel{00}} \: \times \: 1 \cancel{0 0}$

$\color{lime}\sf Profit\: \% \:= \: 1.05 \: \%$
