1,25kg :20 days=0,0625kg eaten a day by 1 person

15kg : 40 people=0,375kg will be eaten by each person

0,375kg : x days =0,0625kg

0,375=0,0625 * x /:0,0625

6=x

The answer is six days.

no of people no of kg of rice no of days

80 100 20

40 15 x

no of people and no of days are in inverse variation

no of kg and no of days are in direct variation

=80/40*15/100*20

answer = 6 days
