Question

Find the cost price when : Q(i)selling price =Rs450,loss=10%

Answer 1

${\huge{\bf{\underline{\red{Answer}}}}}$

Let the Cost price (CP) 100%.

It sold at 10% loss. So, it is sold at (100-10)% = 90% of the Cost price.

90% of the Cost price + 450 = 108% of the Cost price.

18% of the Cost price = Rs 450

$Cost \: price = \frac{450}{18} \times 100 = Rs \: 2500$
