​

Answer 1

Answer:

26055

Step-by-step explanation:

Initial price - 21000

Profit - 5%

New Price - 45000

New Profit - 45000-(21000-5% of 21000)

≈ 45000-(21000-(21000÷20)

= 45000-(21000-1050)

= 45000-199945

= 26055

Answer 2

Given :

Selling price of scooter : ₹21000

Gain percent age : 5%

To find :

The gain percentage of sold at ₹45000.

Solution :

First, we should find the cost price of the scooter.

Cost price of the scooter :

$\sf \dashrightarrow \dfrac{100}{(100 + Gain\%)} \times SP$

$\sf \dashrightarrow \dfrac{100}{(100 + 5)} \times 21000$

$\sf \dashrightarrow \dfrac{100}{105} \times 21000$

$\sf \dashrightarrow \dfrac{20}{21} \times 21000$

$\sf \dashrightarrow \dfrac{20 \times 21000}{21} = \dfrac{420000}{21}$

$\sf \dashrightarrow \cancel \dfrac{420000}{21}= 20000$

Now, we can find the new profit rupees.

New gain rupees :

$\sf \dashrightarrow Selling \: price - Cost \: price$

$\sf \dashrightarrow 45000 - 20000$

$\sf \dashrightarrow Rs.25000$

Now, we can find the new gain percentage.

New gain percentage :

$\sf \dashrightarrow \dfrac{Gain}{Cost \: price} \times 100$

$\sf \dashrightarrow \dfrac{25000}{20000} \times 100$

$\sf \dashrightarrow \dfrac{5}{4} \times 100$

$\sf \dashrightarrow \dfrac{5 \times 100}{4} = \dfrac{500}{4}$

$\sf \dashrightarrow \cancel \dfrac{500}{4} = 125\%$

Hence, the new gain percentage of the scooter is 125%.
