Answer 1

Given:

A dealer made a profit of 25% by selling a car for a 1000 naira.

To find:

The cost price of the car​.

Solution:

Let x be the cost price of the car.

A dealer made a profit of 25% by selling a car. So, the selling price of the car is

`S.P.=x+(25)/(100)x`

`S.P.=x+0.25x`

`S.P.=1.25x`

It is given that the selling price of the car is 1000. So,

`1.25x=1000`

`x=(1000)/(1.25)`

`x=800`

Therefore, the cost price of the car​ is 800.
