Shivangi bought two varieties of pulses, costing Rs. 50 per kg and Rs. 60 per kg each, and mixed them in some ratio. Then she sold the mixture at Rs. 70 per kg. Making a profit of 20 percent. What was the ratio of the mixture?
Show answer & explanation
Correct answer: D
Explanation
Selling Price = ₹70/kg
There is a 20% profit, so the cost price (CP) of the mixture = 70 × 100/120
= 175/3 = ₹58.33/kg
Now, the mixture ratio = Pulse priced at 50 : Pulse priced at 60
= (60 - 58.33) : (58.33 - 50)
= 1.67 : 8.33
= 1 : 5
