By what percentage the net sales forJune increased as compared to May in the Footwear category?

In the Footwear category in June, $$5\%$$ was the rate of product return, this means that the rest $$95\%$$ were the net sales. The total Footwear sales were 111 and hence the net sales will be $$\dfrac{95}{100}\times 111 = 105.45$$ lakhs.

Similarly, for May, the Footwear category total sales were 69, out of which $$6\%$$ were returned and thus $$94\%$$ comprised of net sales. The total net Footwear sales in May were $$\dfrac{94}{100}\times 69 = 64.86$$ lakhs.

Therefore, the percentage increase in Footwear net sales from May to June can be calculated to be $$\dfrac{105.45-64.86}{64.86}\times 100 = 62.58\%$$. The correct answer is option A.
