Answer 1

Answer:

hello dear here is your answer hope it helps you

Step-by-step explanation:

ANSWER

We know that,

SP=CP+Profit

Profit=x%×CP=100x×CP,where x is the percent of profit

So, given SP=360

Profit=20%

Using above equation:-

360=CP+10020×CP

360=CP+5CP

CP=6360×5=300

Therefore, CP=300

Answer 2

Step-by-step explanation:

Cost price of book = Rs 300

Selling price of book = Rs 360

Profit => SP - CP

=> 360 - 300

=> 60.

$Profit\% = Profit \div CP \times 100$

=> 60/300 × 100

=> 20%.
