Solution:-
Number of people 8 x
Stock of rice for days 30 20
This a case of inverse proportion because when number of person increases the stock of rice will last for less days.
⇒ 8*30 = x*20
x = 240/20
x = 12 guests
Now, 8 people were already in the family. Then 12 - 8 = 4 guests joined the family.
