Question

A person sells an article for * 550, gaining 1/10
of its CP. Find gain per cent.​

Answer 1

Answer:

10 %

Step-by-step explanation:

Let the C.P be = x

Gain=x/10

The selling price of the article= Rs. 550

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

This implies that ⇒x+x/10= 550

⇒10x+x/10=550

⇒11x/10=550

⇒11x=550×10

⇒11x=5500

⇒x=5500/11

⇒x=500

Thus, C.P = Rs. 500 and gain =Rs. 50

Gain %= gain/C.P ×100

=50/500×100

10%
