Answer 2

Step-by-step explanation:

Answer 1

Let the cost price of the article be ₹ x

$\bf{= profit = \: 5\% \: of x}$

$\bf \: = 5\% × x$

$\: \\ \bf = (\frac{5}{100} ) × x \: \\ \bf = ( \frac{1}{20} ) × x \\ \bf = ₹ \frac{x}{20}$

Now ,

According to the question

$\bf \: Profit = ₹ 15 \\ \bf= \frac{x}{20} = 15 \\ \bf = x = 15 × 20 \\ \bf= x = 300$$\boxed{ \bf \: therefore \: the \: cost \: price \: is \: 300}$

Answer 2

Given that :

The cost price of a er=Rs. 82000

Percentage depreciated in the rice=8%

$\bf=8\%of \: Cost \: price \\ \bf =8\% of 82000 \\ \bf =8\% × 82000 \\ \bf =( \frac{8}{100} )×82000 \\ \bf =( \frac{8 \times 82000 0}{100}) \\ \bf =8×82000 \\ \bf=Rs.6560$

The price of the scooter after one year

=cost price - depreciation value

=82000 - 6560

=75440

$\boxed{\bf \: The \: value \: of \: the \: scooter \: after \: 1 \: year \: is \: Rs. \: 75,440 \: }$
