00:01
So, according to the question here we have to find the number of birds in the cage.
00:05
So first of all we will assume that the number of rabbits and birds in the cage are x and y respectively.
00:37
That means x rabbits and y birds.
00:40
Okay.
00:41
So, now according to the question we have been given that there are 16 heads in the cage.
00:47
There are 16 heads in the cage.
00:55
Okay.
00:57
So the sum of the heads of rabbits and birds will be equal to 16.
01:03
That means x plus y will be equal to 16.
01:06
This is our equation first.
01:08
Okay.
01:09
So now according to the question it is also given that total feet in the cage, total feet in the cage, they are equal to 38.
01:22
So, we know that rabbit has 4, rabbit has 4 legs.
01:28
Okay.
01:29
So total number of rabbits are x.
01:31
Each rabbit has 4 legs.
01:33
That means the total feet of rabbits are 4x plus every bird has 2 legs and number of birds are y.
01:40
Okay.
01:40
So total number of feet of the birds will be 2y and the sum will be equal to 38...
