Option 1: INR 340
Option 2: INR 330
Option 3: INR 350
Option 4: INR 360
Correct Answer: INR 330
Solution :
Given,
The cost of two varieties of tea is INR 300 and INR 375, respectively.
Both varieties of tea are mixed together in a ratio 3 : 2.
So, the cost of the (3 + 2) i.e., 5 kg of the mixed tea = (3 × 300) + (2 × 375) = 900 + 750 = INR 1650
$\therefore$ The cost of the mixed tea per kg = $\frac{1650}{5}$ = INR 330
Hence, the correct answer is INR 330.
