If two types of pulses costing ₹97 per kg and ₹105 per kg are mixed in the ratio of 5 ∶ 3, then what is the cost of the resulting mixture?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. ₹100.
Cost of Pulse A in mixture = 5 × 97 = 485
Cost of Pulse B in mixture = 3 × 105 = 315
Total cost = 485 + 315 = 800
Total quantity = 5 + 3 = 8 kg
Cost per kg of mixture = 800/8 = 100
