A farmer increased his number of animals by 25 %.

He now has 240 animals.

How many animals had he at first?

192

Step-by-step explanation:

Let the original number of animals be 'x'

% increment = 25%

Increment = 25x/100=0.25x

New number of animals = x + 0.25x

240 = 1.25x

x = 192

180 animals

Step-by-step explanation:

The number of animals increased by 25%

The farmer now has 240 animals.

25% / 100% x 240

0.25 x 240

60.

This means 25% increase added 60 animals to his farm.

Therefore, animals he had at first will be

240 - 60

180

He had 180 animals before the 25% increase
