Step-by-step explanation:
Total no. of horses and chicken=24
C+H=24
Total no. horses be =24-C
Total no. legs=66
---66=4(24-C)+2C { As horses have 4 legs and chicken has 2 legs}
66=96-4c+2c
66-96=-2c
-30=-2C
Chicken=15
Therefore no. horses=24-C
=24-15
=9horses
There fore no. of chicken legs=15×2 = 30 legs
Therefore no. of horse legs=9×4=36 legs
