In what ratio must a grocer mix two varieties of pulses costing Rs. 16 and Rs. 21 per kg, respectively, so as to get a mixture worth Rs. 18 per kg?
Show answer & explanation
Correct answer: B
Explanation
Given:
Price of the first dal = Rs. 16/kg
Price of the second dal = Rs. 21/kg
Price of the mixture = Rs. 18/kg
Formula:
Ratio of the mixture = (Higher price − Mixture price) : (Mixture price − Lower price)
Ratio = (21 − 18) : (18 − 16) = 3 : 2
Ratio of pulses = 3 : 2
