1. Two blends of tea costing $2.80 and $3.20 per kg respectively, are mixed in the proportion 2 : 3. The mixture is sold at $4.80 per kg. What was the percentage of profit?

  • A. 57.9
  • B. 57.9
  • C. 57.9
  • D. 57.9

Answer: Option A

Explanation:

Let the amount of tea blends be 2T and 3T respectively.

Then total cost  = 2T x $2.8 + 3T x $3.2 = $15.2T

Total sell = (3T + 2T) x $4.8 = $24T

So, profit = (24T - 15.2T) / 15.2T x 100% = 57.9%
