In what ratio must a grocer mix two varieties of pulses costing ₹60 and ₹75 per kg, respectively, so as to get a mixture worth ₹65 per kg?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 2 : 1.
Cost of the first variety = ₹60 per kg
Cost of the second variety = ₹75 per kg
The desired cost of the mixture = ₹65 per kg
Difference between the cost of the second variety and the mixture = ₹75 - ₹65 = ₹10
Difference between the cost of the first variety and the mixture = ₹65 - ₹60 = ₹5
Ratio = 10/5 = 2 : 1
