- Number of cows ➢ 454
To Find :-
Which of the following is a good estimation of how many horses and cows he had altogether?
600 horses and cows
700 horses and cows
650 horses and cows
750 horses and cows
850 horses and cows
Calculation :-
Here, We will simply add up the number of animals ( cows and horses ) and then we will round it off to it's nearest 'tens' places.
⇒ Total number of animals = number of horses + number of cows
Substituting the values given, We get,
⇒ Total number of animals = 305 + 454
⇒ Total number of animals = 759
Now, when we round it off to it's nearest 'tens' places, We get,
⇒ Round off 759 = 750
Since, We can see that, 4th option from the list of option given, is 750. Therefore 750 is the answer.
