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 ?
Answer & explanation
Correct answer: option 1
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
