Answer:
the number of new cattle that he had bought = 19
Step-by-step explanation:
Cattle the farmer had = 38
Number of days the fodder is sufficient for = 60 days.
38 cattle will feed on 60 days of fodder.
Total fodder available = 38 x 60
Some cattle was added.
Let the added cattle = x
So the total cattle now = 38 + x
Number of days the fodder is sufficient now = 40 days
Total food available = (38 + x) x 40
Therefore,
38 x 60 = (38 + x) x 40
38 + x = 57
=> x = 19
