Question

PLEASE GIVE WITH PROPER EXPLANATION ​

Answer 1

Step-by-step explanation:

Cp=20

Sp=16

Cp=sp

16=20

gain= 20-16

4

gain%= 4/16*100

=25%

Answer 2

Solutions:-

Let the Cp of 1 card is x

Then, the Cp of 20 cards is 20x

Given,

Sp of 16 greeting cards = 20x

$\therefore \: Sp \: of \: 1 greeting \: cards = \: \ \ \frac{20x}{16}$

Gain = Sp-cp

$= > \ \frac{20x}{16} - x \\ =</strong><strong>></strong><strong> \frac{20x - 16x}{16} \\ = > \frac{4x}{16 } \\ = > \frac{x}{4} \\ </strong><strong>G</strong><strong>ain\% = \frac{x}{4} \times \frac{1}{x} \times 100 \\ </strong><strong>G</strong><strong>ain\% = 25\%$
