Question
The cost of production of Track suits by Nike is
approximately what percent more than the cost of production of Shoes by Reebok?Solution
Production cost of Track suits by Nike = 3/5 of 25% of 4crore = 0.6 crores Production cost of Shoes by Reebok = 4/9 of 18% of 4crore = 0.32 crores Therefore, required % = (0.6 – 0.32)/0.32 × 100 = 87.5% (88% approx)
