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?

The cost prices of a pen and a notebook are ₹600 and ₹4,000, respectively.

Total cost prices of a pen and a notebook = 600+4000 = ₹4600

If the pen and the notebook are sold at losses of 20% and 32%, respectively.

Loss on pen = 600 of 20%

= $$600\times\frac{20}{100}$$

= ₹120

Loss on notebook = 4000 of 32%

= $$4000\times\frac{32}{100}$$

= ₹1280

Total loss on pen and notebook = ₹120+₹1280 = ₹1400

Approximate percentage of total loss incurred through the two sales made = $$\frac{total \ loss}{total \ cost \ pirce}\times100$$

= $$\frac{1400}{4600}\times100$$

= $$\frac{1400}{46}$$

= 30.43% (approx.)
