its your answer hope u understood

Answer 2

Answer:

24 article

Step-by-step explanation:

$profit \: percentage \: = \frac{sp - cp}{cp} \times \times 100$

$20 = \frac{80 - cp}{cp} \times 100$

$cp =rs. \: \frac{200}{3}$

or else assume CP = 100 ; 20% profit SP = 120.

If this 120 is 80 what is 100

$cp = \frac{80}{120} \times 100 = rs. \: \frac{200}{3}$

$sp \: of \: each \: article = \frac{80}{20 } = rs \: 4$

$cp \: of \: each \: article = \frac{200}{3 \times 20 } =rs. \: \frac{10}{3}$

If he purchase for 80 rupees at CP

$\frac{80}{ \frac{10}{3} } = \: 24$
