Answer 1

At a certain time in a deer park, the number of heads and the number of legs of deer and human visitors were counted and it was found there were 39 heads & 132 legs.

PLEASE MARKED IT AS BRILLIANT

Answer 2

Let there be x deer and y human visitors in the park at the given time.

As a deer and a human each has one head, we get

x + y = 41

As a deer has 4 legs and a human has 2 legs, we get

4x + 2y = 136 = 2x + y = 68

Subtracting (i) from (ii), we get

x = 27.

Substituting x = 27 in (i), we get

27 + y = 41 = y = 14.

Hence, there were 27 deer and 14 human visitors in the park.
