1.	By selling an article for Rs 240, a man makes a profit of 20%.What is his C.P.? What would his profit percent be if he sold the article for Rs 275?
Answer» Let CP = Rs. x SP = Rs. 240 Let profit be Rs. P. Now, profit % = 20% Since Profit % = (Profit/CP) x 100 20 = (P/x) x 100 P = 20x/100 = x/5 Profit = SP – CP = 240 – x P = 240 – x x /5 = 240 – x 240 = x + x/5 240 = 6×15 x = 1200/6 x = 200 So, CP = Rs. 200 New SP = Rs. 275 and CP = Rs. 200 Profit % = {(SP – CP)/CP} x 100 {(275 – 200)1200} x 100 = (75/200) x 100 = 7500/200 = 37.5%

Answer»

Let CP = Rs. x SP = Rs. 240

Let profit be Rs. P.

Now, profit % = 20%

Since Profit % = (Profit/CP) x 100

20 = (P/x) x 100

P = 20x/100 = x/5

Profit = SP – CP = 240 – x

P = 240 – x

x /5 = 240 – x

240 = x + x/5

240 = 6×15

x = 1200/6

x = 200

So, CP = Rs. 200

New SP = Rs. 275 and CP = Rs. 200

Profit % = {(SP – CP)/CP} x 100

{(275 – 200)1200} x 100 = (75/200) x 100

= 7500/200

= 37.5%
