Question

A trader by selling each apple for Rs.6 made a profit of 20% . what is the cost of 100 apples ? ​

Answer 1

Step-by-step explanation:

Given: SP: Rs.6 for 1 apple

Profit%-20%

To find: Cost of 100 such apples

• CP= SP- Profit
• =Rs.6-20% of 6
• $6 - \frac{20}{100} \times 6 \\ 6 - \frac{1}{5} \times 6 \\ 6 - \frac{6}{5} \\ \frac{30 - 6}{5} = \frac{24}{5} = 4.8$
• CP=RS.4.8
• CP OF 100 APPLES= 4.8×100=RS 480
• SP OF 100 APPLES= 480+20% OF 480
• $480 + \frac{20}{100} \times 480 \\ 480 + \frac{480}{5 } \\ 480 + 96 = 576$
• SP OF 100 apples=Rs.576
