(40*4*15000) / (8000*5) = 60

A very easy one!!
8000 dollars sufficient for a family of 4 members for 40 days => we must find daiy dollar per member (rate)
8000/4 = 2000 dollars for 40 days => 50 dollars per day
How many days for 5 members totalling 15000 with 50 dollar per member a day?
15000/5 = 3000 dollars per member; therefore number of days = d = 3000/50 = 60 days
Answer is (E)
