hello
CORRECTION :- the number of legs can never be less than number of heads as it would imply that some animals are devoid of legs which is impractical . so I have made slight changes in the Question . if there is some mistake do comment
===============================
let the total number of goats be x
so total number of hens = 32-x
1 goat has 4 legs
1 hen has 2 legs
ATQ
4x + 2( 32 -x) = 94
4x - 2x + 64 = 94
2x = 94 - 64
2x = 30
x = 15
the number of hens is 32 - 15 = 17
