Question

If a person sells an article for 360, gaining 1/5 th of its
CP, find the gain per cent.​

Answer 1

Answer:

20%

Step-by-step explanation:

Let the C.P be = x

Gain=x/5

The selling price of the article= Rs. 360

We know that, S.P= C.P + Gain

 This implies that ⇒x+x/5= 360

⇒5x+x/5=360

⇒6x/5=360

⇒6x=360×5

⇒6x=1800

⇒x=1800/6

⇒x=300

Thus,

C.P = Rs. 300

Gain =Rs. 60

Gain %= gain/C.P ×100

            =60/300×100

             =20%
