Question

On selling an article for Rs. 171,a shopkeeper gains a profit equal to the percentage of cost price of the article. Find the cost price of the article.​

Answer 1

Ummm sorry don’t know

Answer 2

Answer is 90

$\%profit = \frac{sp - cp}{cp} \times 100$

Here mentioned profit is numerically equal to its cost price, so

=> cp= [(171-cp)cp]100

=>(cp)²=17100-100cp

=>(cp)²+100cp-17100= 0

=> (x+190) (x-90)

C.P cannot be negative.

So,

Cp= +90

I HOPE IT'S HELPFUL :)
