A person sells an article for ₹ 750 gaining 1/10 of its C.P. Find its gain%​

Answer»

Step-by-step explanation:

Let the CP =X

Gain=X/10

The SELLING price of article=RS 750

A person sells an article for 3 750 gaining 1/10 of its C.P. Find its gain%.​

Answer»

ANSWER:

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%
