The cost prices of a pen and a notebook are ₹600 and ₹4,000, respectively. If the pen and the notebook are sold at losses of 20% and 32%, respectively, what will be the approximate percentage of total loss incurred through the two sales made?

30.43%

Cost price of notebook = 4000

cost price of pen = 600

discount on pen = 20%

Discount on notebook = 32%

So SP of pen = 80% of 600 = 480

SP of notebook = 68% of 4000 = 2720

Total CP = 600 + 4000 = 4600

Total SP = 2720 + 480 = 3200

Loss% = (4600 - 3200) × \(\frac{100}{4600}\) = 30.43%
