A shop gives 20% discount. What would the sale price of each of these be?

(a) A dress marked at Rs. 120

(b) A pair of shoes marked at Rs. 750

(c) A bag marked at Rs. 250

Answer:

A shop gives 20% discount of every items

(a) Let us suppose that the price of dress is Rs. x

According to condition

Discount value = Discount % of marked price

= 20% of 120                {marked price = 120 Rs}

\[=\frac{20}{100}\times 120\]

Discount value =Rs. 24

Selling price (x) = Marked price \[-\]Discount value

=Rs.120\[-\]Rs.24

=Rs.96

The Selling price of dress (x) = Rs 96

(b) Let us suppose that the selling price of a pair of shoes is Rs. x. According to condition,

Discount value = Discount % of marked price

=20% of 750            {marked price = 750 Rs.}.

\[=\frac{20}{100}\times 750\]

Discount value = Rs. 150

Selling price (x) = Marked price \[-\] Selling price

=Rs.750\[-\]Rs. 150

The selling price of shoes (x) = Rs. 600

(c) Let us suppose that the selling price of bag be Rs. x

According to condition,

Discount value = Discount % of marked price

= 20% of 250            {marked price = 260 Rs.}

\[=\frac{20}{100}\times 250\]

Discount value = Rs. 50

Selling price (x) = Marked price \[-\] Discount value

=Rs.250\[-\]Rs.50=Rs.200

Selling price of bag (x) =Rs. 200
