A sold a mobile phone to B at a gain of 25% and B sold it to C at a loss of 10%. If C paid ₹5,625 for it, how much did A pay (in ₹) for the phone ?

5,000

Given:

A sold a mobile phone to B at a gain of 25%

B sold the mobile to C at a loss of 10%

Total money paid by C = Rs. 5625

Calculation:

Let, the A paid for the mobile phone = x

So, x × (\(\frac{125}{100}\) ) × (\(\frac{90}{100}\) ) = 5625

⇒ x = 5625 × (\(\frac{100}{125}\)) × (\(\frac{100}{90}\))

⇒ x = 5000
