Answer: On selling an article for Rs 250, a boy gains Rs 50. His gain% is 25%.

Answer 2

• Given

• Selling price = Rs. 250
• Gain (Rs.) = Rs. 50

• To find

• Gain% = ?

• Solution

• Firstly, for finding gain% we have to find cost price.

$\red{\bigstar}$ Cost price = Selling price - Profit

$\implies$ Rs. 250 - Rs. 50

$\implies$ Rs. 200

• Cost price = Rs. 200

Formula to find Gain% -

$\red{\bigstar}$ $\large\boxed{\sf{\blue{Gain\% = Gain/C.P × 100}}}$

Substitute the given values.

$\implies$ 50/200 × 100

$\implies$ 25%

• Gain % = 25 %
