Question

A sells an article to B at a profit of 20 percent and B sells it to C at a loss of 10 percent . lf C pays 216 for the article . find the cost price for A
​

Answer 1

Step-by-step explanation:

c pays 216 for article it means 216 is the sp of b

• now, we can find the cp of b = 100 × sp/100 - loss%
• then 100 × 216/100 - 10
• 21600/90
• 240rs

240rs is the cp of b

it means 240 is the sp of a

• now, we can find cp of a = 100 × sp/100 + gain%
• 100 × 240/100 + 20
• 24000/120
• 200rs ans

hence, the cost price of A is rs200
