Question

12 cow can graze a field in 56 days. How long would 7 cows take to graze the same field

Answer 1

12 cow can graze a field in 56 days
1 cow can graze the field in 56×12 days
7 cow can graze the field in
$56 \times 12 \div 7 = 96$
days

Answer 2

time taken by 12 cows = 56 days

time taken by 1 cow = 56*12 (inversely propotional)

time taken by 7 cow = 56*12/7

                                  = 96
