• Profit : 20%

To Find:

Cost price of rice cooker.

Solution:

Case 1: Find the selling price in percentage.

Profit :- 20%

Selling price :- 100 + 20

$\dashrightarrow\: \underline{\boxed{\bf{\orange{120\%}}}}$

Case 2: Find the cost price.

Selling price = 120%

Selling price = Rs. 768

$\dashrightarrow\: \sf\ 120\% = Rs. 768$

$\dashrightarrow\: \sf\ 1\% = 768÷20 = 38.4$

By using formula of Cost price:-

$\underline{\boxed{\bf{\pink{CP = (SP × 100)}}}}$

$\dashrightarrow\: \sf\ 100\% = 3.84 × 100$
