Answer:
2 days
Step-by-step explanation:
If the number of animals increases, then it will take fewer days to last.
Then the two quantities are in inverse proportions.
Let the required number of days be p.
Where,
and (let)
=> 20 × 3 = 30 × p
=> 60 = 30p
=> p = 60/30
=> p = 2
Hence the required number of days = 2.
