GIVEN

A 30% Discount Reduces The Price Of A Commodity by $ 90.

TO FIND

Price of the commodity After the discount of 20%.

SOLUTION

We can simply solve the above problem as follows;

Let the original price of the commodity be $ x

ATQ,

$x - 30\%x = x - 90$

$= x - \frac{30x}{100} = x - 90$

= 100x - 30x/100 = x - 90

= 70x/100 = x -90

= 70x = 100x - 90

= -30 x = -90

x = $300

So, original price of the commodity is $300.

Discount = 20%.

Price after discount = 300 - (20% of 300)

= 300 - (0.2×300)

= 300- 60

= 240.

Hence, The reduced price of the commodity is $240.
