How many liters of oil at Rs.40 per liter should be mixed with 240 liters of a second variety of oil at Rs.60 per liter so as to get a maximum whose cost is Rs.52 per liter ?
145 ltrs
Incorrect Answer150 ltrs
Incorrect Answer155 ltrs
Incorrect AnswerExplanation:
Apply Allegation Method and first calculate the ratio in which they have to be mixed.
= 8 : 12 = 2 : 3
Thus, the two varieties of oil should be mixed in the ratio 2 : 3.
So, if 240 liters of the second variety are taken,
then 160 liters of the first variety should be taken.
Hence, option 4 is the correct answer.
