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 ?
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.
