Question

by selling an article for rs 360,a man makes a profit of 20% . what would his profit percent be if he sold the article for rs 400​

Answer 1

Answer:

Selling Price (SP) = 3600

Profit = 20%

To determine the Cost Price (CP)

Profit % = (SP - CP) / CP /100

20 = [(3600-CP) / CP ] X 100

20 CP / 100 = 3600 - CP

20 CP + 100 CP = 360000

120 CP = 36000

CP = 360000/120

CP = 3000

Now, if sold for 3150, profit in rupees = Rs 150

Profit % = [150/3000] X 100 = 5%

Answer 2

Step-by-step explanation:

Using unitary method

Let cp be 100,sp will be 120

Cp Sp

100 120

? 3600

(3600*100)/120=3000

When Sp is 3150,P=150

P%=(150/3000)*100=5%
