A man (A) sold goods to B at 25% profit, B sold to C at 20% profit, C sold to D at 28% profit. If D purchases it at Rs.9600. Then find the cost price of the article for A?

5000

A's cost price × [1+\(\frac{25}{100}\)] × [1+\(\frac{20}{100}\)] × [1+\(\frac{28}{100}\)] = 9600 (D's price)

A's cost price × \(\frac{125}{100}\) × \(\frac{120}{100}\) × \(\frac{128}{100}\) = 9600

A's cost price × \(\frac{5}{4}\) × \(\frac{6}{5}\) × \(\frac{32}{25}\) = 9600

A's cost price = \(\frac{9600 × 25}{48}\) = 5000
