8 kgs of tea at Rs. 4 per kg and 6 kgs of tea at Rs. 9 per kg are mixed together and the mixture is sold at a 15% profit. What is the selling price per kg of the mixture?

8 kgs of tea at Rs. 4 per kg and 6 kgs of tea at Rs. 9 per kg are mixed together and the mixture is sold at a 15% profit. What is the selling price per kg of the mixture? Correct Answer Rs. 7.06

C.P of 8 kgs of tea at the rate of Rs. 4 per kg = 8 × 4 = Rs. 32

C.P of 6 kgs of tea at the rate of Rs. 9 per kg = 6 × 9 = Rs. 54

Total cost price of (8 + 6) kgs of tea mixture = Rs. 86

Given: profit = 15% of C.P = (15/100) × 86 = Rs. 12.9

Total S.P = CP + Profit = Rs. (86 + 12.9) = Rs. 98.9

Total quantity of tea mixture sold = 14 kgs

Therefore, S.P./kg of tea = Rs. (98.9/14) = Rs. 7.06
