Question

in a zoo there are deers and ducks the heads are 180 and legs are 448 what us number of deers

Answer 1

Let x be the number of deers in the zoo
Then (180-x)be the number of ducks, as each animal and bird has one head.
Now duck has 2 legs and deer has 4 legs so
4x+2(180-x)=448
2x+360=448
X=44
No of deers=44
And no of ducks=(180-44)=136

Answer 2

The answer is given below :

Let us consider that there are x number of deer and (180 - x) number of ducks in the zoo.

Then,

4x + 2(180 - x) = 448

=> 4x + 360 - 2x = 448

=> 2x = 88

=> x = 44

So, number of deer is 44

and

number of duckes is (180 - 44) = 136.

Thank you for your question.
