This Question has 1 answers.
Let the two varieties of tea be A and B respectively
Suppose the businessman mixes 2 kg of tea of type A and 5 kg of tea of type B
Mixture of both types of tea = 7 kg
Cost of 2 kg of type A tea at Rs. 45 per kg = 2 × 45 = Rs. 90
Cost of 5 kg of type B tea at Rs. 31 per kg = 5 × 31 = Rs. 155
Cost of 7 kg of mixture = 90 + 155 = Rs. 245
⇒ Cost of 1 kg of mixture = 245/7 = Rs. 35
SP of 1 kg of mixture = Rs. 40
Profit = 40 – 35 = Rs. 5
⇒ Profit % = (5/35) × 100 = 100/7
∴ Profit% = $(14\frac{2}{7})$
