Question

A man sold a radio set for Rs250and gained one ninth of its cost price.
Find:
1.cost price
2.the profit percent

Answer 1

Answer:

1.Rs225

2.11.11%

Step-by-step explanation:

let cost price be x

then selling price =profit+cost price

=1/9 x +x

=10/9 x

therefore, selling price =10/9 x

250=10/9 x

x=250×9/10

. x=225

therefore, cost price =Rs225

2. profit percent =profit /cost price ×100

profit=1/9 x

=1/9×225

=Rs 25

profit percent =25/225×100

=100/9%=11.11%
