In what ratio should sugar costing ₹52 per kg be mixed with sugar costing ₹73 per kg so that by selling the mixture at ₹87.1 per kg, there is a profit of 30%?

Correct option is B

Given:

Cheaper = ₹52/kg, Dearer = ₹73/kg, SP of mixture = ₹87.1/kg, Profit = 30%

Formula Used:

CP of mixture $$=\dfrac{\text{SP}}{1+\text{Profit\%}}$$​​

Solution:

CP of mixture $$=\dfrac{87.1}{1.30} =67$$​​

Alligation: (₹52 : ₹73) = (73 − 67): (67 − 52) = 6 : 15
