Answer:
cow can graze ‘g units of substance in one day.
45 cows can graze in 13 days .
Work Done = Rate x time.
= (45g x 13 )
The same work is done in 9 days
Work done = rate x time
(45 x 13 ) = rate x 9
Rate x 9 = 45 x 13
Dividing both sides by 9
Rate x 9/9 = (45 x 13) ÷ 9
Rate = 5 x 13
Rate = 65 g
65 cows can graze in 9 days .
Ans : 65 cows
