1 (25%)
বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Solution:
Cost of first variety = 250 Taka/kg
Cost of second variety = 350 Taka/kg
Ratio = 3:2
Cost price of mixture = {(3×250) +(2×350)}/(3+2)
= 1450/5
= 290 Taka/kg
Profit = Selling price - Cost price
= 360 - 290
= 70 Taka/kg
Profit percentage = (70/290) × 100%
= 24.13%
= 25%
