Three different types of pulses costing ₹180, ₹240 and ₹200 per kg, respectively, are mixed in the ratio 1 : 5 : 4. What will be the cost for 1 kg of the mixture?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e ₹218.
Prices per kg:
Type 1 = ₹180
Type 2 = ₹240
Type 3 = ₹200
Mixing ratio = 1 : 5 : 4
(Total parts = 1 + 5 + 4 = 10)
Cost of mixture per kg = (1 × 180 + 5 × 240 + 4 × 200)/10 = (180 + 1200 + 800)/10 = 2180/10
= ₹218
