Detailed Solution
Download Solution PDFGiven:
Selling Price of both laptops = ₹4680 each
Gain on one = 30%
Loss on other = 40%
Formula used:
CP = SP × 100 / (100 ± Gain or Loss%)
Total CP = CP₁ + CP₂
Overall Loss% = (Total CP - Total SP) / Total CP × 100
Calculation:
CP of first laptop (gain 30%) = 4680 × 100 / 130 = 3600
CP of second laptop (loss 40%) = 4680 × 100 / 60 = 7800
Total CP = 3600 + 7800 = 11400
Total SP = 4680 × 2 = 9360
Loss = 11400 - 9360 = 2040
Loss% = (2040 / 11400) × 100 = 17.89%
∴ Overall loss = 17.89%
