33

A buys an article for Rs.900 and sells it to B at a profit of 25%. B sells it to C, who sells it for Rs.1,350, at a loss of 10%.

Now, SP for A =\(\frac{125}{100}\) × 900 = 1125 = CP for B

ATQ, 

 B sells it to C, who sells it for Rs.1,350, at a loss of 10%

SP for B × \(\frac{9}{10}\) = 1350 

SP for B = 1350 ×  \(\frac{9}{10}\)

SP for B = 1500

Profit% = (1500 - 1125) ×\(\frac{100}{1125}\) = 33.33% = 33%
