A) 26 B) 27 C) 28 D) 29 E) 30
Let number of hens = h and number of cows = c   number of heads = 48   =&gt; h + c = 48 ---(Equation 1)   number of feet = 140   =&gt; 2h + 4c = 140   =&gt; h + 2c = 70 ---(Equation 2)   (Equation 2) - (Equation 1) gives   2c - c = 70 - 48   =&gt; c = 22   Substituting the value of c in Equation 1, we get   h + 22 = 48   =&gt; h = 48 - 22=
