Step-by-step explanation:
a. daily requirement of milk = 4 liters
15 liters of milk is present
this 15 liters of milk will be used up in days
= 3(3/4) days , so after 3 days only more milk will be required to purchase.
b. daily milk consumption is reduced to half = 2 liters
Now, 15 liters of milk will be used up in = 7.5 or 7(1/2) days.
Hence now milk will be purchased after 7 days.
