Question 47

Cost of Type - I Liquid is Rs. 32 per ltr ;
Cost of Type - II Liquid is Rs. 40 per ltr.
If both types of liquids are mixed in the ratio 3 : 5 to create a new type of Liquid (named Type - Ill), then determine the cost per ltr of the the newly created Type - Ill Liquid, considering the fact that there have been no other costs involved in creation of the new liquid ?

We are given that:

Type I → Rs. 32/ltr

Type II → Rs. 40/ltr

Ratio = 3 : 5

We can simply solve this using the weighted average method.

Cost = $$\dfrac{\left(32\times3\right)+\left(40\times5\right)}{3+5}=\dfrac{96+200}{8}=\dfrac{296}{8}=37$$

Hence, the answer is Rs. 37 per litre.
