Answer 2

Correct Question:

Rohan buys an old washing machine for Rs.5500 and spends Rs. 1000 on its repairs. If he sells the washing machine for Rs. 7800 find his gain percentage.

Answer:

The Gain % made by Rohan is 20%.

Step-by-step explanation:

Given :

Buys the washing machine = Rs. 5500

Spends = Rs. 1000 on repairs

Sells the washing machine at = Rs. 7800

To find :

The gain percentage

Solution :

Cost Price = Rs. 5500

Overheads = Rs. 1000

Total cost price = 5500 + 1000

$\implies$ Rs. 6500

$\rule{300}{1.5}$

Here -

• Cost Price = 6500
• Selling Price = 7800

$\implies$ 6500 < 7800

$\implies$ CP < SP

$\therefore$ It is a gain.

$\rule{300}{1.5}$

★ Gain % -

${\boxed{\sf\:{Gain\% = \frac{SP - CP}{CP} \times 100}}}$

$\tt{\implies} \: Gain\% = \dfrac{7800 - 6500}{6500} \times 100 \\ \\ \tt{\implies} \: Gain\% = \dfrac{1300}{6500} \times 100 \\ \\ \tt{\implies} \: Gain\% = \dfrac{130000}{6500} \\ \\ \tt{\implies} \: Gain\% = 20\%$

Gain % = 20%

$\therefore$ The Gain % made by Rohan is 20%.
