Aditya sells two wrist watches from his personal collection for ₹12,600 each. On the first watch, he gains 26% and, on the second, he loses 10%. Find the overall gain or loss percentage.
Answer & explanation
Correct answer: option 2
Gain on first = 26% = \(\frac{63}{50}\)
Loss on second = 10% = \(\frac{9}{10}\)
CP SP
First = 50 63
Second = 10 9
As the selling price is same for both the watches =
CP SP
First = 50 63
Second = (10 9 ) × 7
CP SP
First = 50 63
Second = 70 63
