Answer / raviteja900
Number of cows = a
Number of birds = b
so total number of eyes are
=> 2a + 2b = 172
total number of legs are
=> 4a + 2b = 344
so solving these equations we get
0 birds and 86 cows

Answer / sheeba
2a+2b=172-----------eqn(1)
4a+2b=344-----------eqn(2)
substitute both
we get a=86(a=cow)
and b=0(b=birds)
so 86 cows and 0 bird
