Question

45 cows can graze a field in 13 days. How many cows will graze the same field in 9 days?

Accepted Answer

Solution:-

45 cows can graze a field in 13 days

1 cow can graze a field in = (45 × 13) days … [less cows, more days]

∴Number of cows required to graze a field in 9 days = (45 × 13)/ 9

= 65 cows … [More cows, less days]

Hence, 65 cows required to graze a field in 9 days.
