Answer:

4 days

Step-by-step explanation:

MORE ANIMALS, LESS TIME

SO, IT IS A CASE OF INVERSE PROPORTION

Let the time the food will last be x.

Then, 20*6=(20+10)*x

Or,120=30x

Or,120/30=x

Or, 4 days=x

Answer:

4 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.

 \because x_1y_1 = x_2y_2

Where,

 x_1 = 20, \: y_1 = 6, \: x_2 = 3 and  y_2 = p (let)

=> 20 × 6 = 30 × p

=> 120 = 30p

=> p = 120/30

=> p = 4

Hence the required number of days = 4.
