Question

Mr. Shekhar sold his bike for rs. 10500 at a profit of 5%. Find the C.P. of the bike.

Answer 1

here is the ans. bt i m not sure

Answer 2

let c.p = x


s p of bike =Rs10500


Profit=5%

$profit \%= \frac{s.p - c.p}{c.p} \times 100$

so
$profit\% = \frac{10500 - x}{x} \times 100$

=>
$5 = \frac{10500 - x}{x} \times 100$


=>
$\frac{5}{100} = \frac{10500 - x}{x}$

=>

$5x = (10500 - x)100$
=>

$5x = 1050000 - 100x$
=>
105x=1050000

=>

x=10000 Rs


hence


c.p of bike = 10000 Rs
