How many chickens did the farmer have at first?

Question

a farmer had the same number of chickens and ducks after selling 10 chickens and 24 ducks the remaining ratio of chickens to ducks is 3:1 how many chickens did the farmer had at first?

Answer 1

Let number of chicken be x

Let the number of ducks be y

after selling chicken, the remaining will be × - 10

after selling ducks, the remaining will be y - 24

equate their ratios to 3 : 1

since they have equal numbers at first, then x = y

then you have a value of x = 31

the answer is 31
