A wholesaler blends two varieties of tea, one costing Rs. 60 per kilogram and another costing Rs. 105 per kilogram. The respective ratio of quantities they were mixed in was 7 : 2. If he sold the mixed variety at Rs. 100 per kilogram, how much was his profit percentage ? 1). $$34\frac{2}{7}$$ 2). $$38\frac{2}{5}$$ 3). $$32\frac{2}{5}$$ 4). $$42\frac{6}{7}$$
Let wholesaler mixed 7 kg and 2 kg of tea of variety 60 Rs/kg and 105 Rs/kg respectively. Cost of tea of variety 60 Rs/kg=$60\times7$. =Rs. 420. Cost of tea of variety 105 Rs/kg=$105\times2$. =Rs. 210. Total cost=420+210. =630. Selling price=$9\times100$. =900. Profit percentage=$\frac{900-630}{630}\times100$. =$\frac{300}{7}$. =$42\frac{6}{7}$. Hence, Option D is correct.
