There are two types of dal. Type 1 dal costs ₹100 per kg and type 2 dal costs ₹120 per kg, respectively. If both the dal are mixed in the ratio 2 : 3, find the cost of the mixed dal per kg.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e ₹112.
Type 1 dal = ₹100/kg
Type 2 dal = ₹120/kg
Mixing ratio = 2 : 3
Total parts = 2 + 3 = 5
Weighted average cost = (2 × 100 + 3 × 120) / 5 = (200 + 360) / 5 = 560 / 5 = ₹112 per kg
