Question

A sells an article to B at a profit of 20%. B sells it to C at a profit of 5%. what does it cost to A if C has paid ₹624?

Answer 1

Answer:

A gain = 20%

sp = x

cp = 100 /120 × X

= 100x /120

B sp = 100x /120

gain = 5%

cp = 100 / 105 × 100x/120

200 x/ 12600

624 = 200x / 12600

624 ×12600 /200 = x

63 × 624 = x

39312 = x
