Question

12. Oranges are bought at 6 for 20 and sold at 4 for 18. Find the gain or loss per cent​

Answer 1

Answer:

There is a 35% gain.

Step-by-step explanation:

Here is the solution:

----------------------------------------

Find the cost of 1 orange:

6 oranges = Rs 20

1 orange = 20 ÷ 6 = Rs 10/3

Find the selling price of 1 orange:

4 oranges = Rs 18

1 orange = 18/4 = Rs 9/2

Find the profit / loss:

Since 9/2 > 10/3 ⇒ It is a profit

Profit = Selling Price - Cost Price

Profit = 9/2 - 10/3 = Rs 7/6

Find the profit percentage:

Profit percentage = (profit ÷ cost price) x 100

Profit percentage = ( 7/6 ÷ 10/3 ) x 100 = 35%

Answer: There is a 35% gain.

Answer 2

Answer:

$\underline{\textsf{\textbf{ Gain \: percent}}} = 35.135%</p><p></p><p>⤵️</p><p></p><p><strong>Step-by-step explanation:</strong></p><p></p><h2><strong><u>Question:</u></strong></h2><p></p><ul><li>Oranges are bought at 6 for 20 and sold at 4 for 18.

S.P of 4 oranges= Rs.18

S.P of 1 orange=$\displaystyle\frac{18}{4}$ = 4.5Rs.

To find:

$\texttt \red{Gain \: percent}$

Formula:

$\underline{\textsf{\textbf{ Gain \: percent}}}$ = $\displaystyle\frac{S.P-C.P}{C.P}$ $\times$ 100

Solution:

$\underline{\textsf{\textbf{ Gain \: percent}}}$ = $\displaystyle\frac{4.5-3.33}{3.33}$ $\times$ 100

$\underline{\textsf{\textbf{ Gain \: percent}}}$ = $\displaystyle\frac{1.17}{3.33}$ $\times$ 100

Gain percent= 35.135%
