Question

a trader bought an article for Rs X and sold it for Rs 52 thereby along profit of X-10 percent on his outlay .calculate the cp

Answer 1

solve

we know that

profit is s.p -c.p

so, 52-x = profit

and profit % = profit/c.p *100

So, (52-x)/x * 100 = x - 10

On transferring denominator x we get

(52-x)*100=(x-10)*x

After opening brackets we get (in photo below)

Remember c.p is positive so 40 rs is ans.
