Question

90 cows graze a field in 18 days.How many cows will graze the field in 15 days?​

Answer 1

Answer:

Step-by-step explanation:

More the cows, less the number of days the field can be grazed.

So, this is a case of inverse variation.

Let x be the number of cows which can graze the field.

Then x:45 ::13:9

So, 9(x) = 45 (13)

x = 45(13)/9 = 65.

Hence 65 cows can graze the field in 9 days

Answer 2

Answer:

the answer is 65 cows gaze the field in 15 days
