  1. Answer:

    (B) 7

    Step-by-step explanation:

    let the no. of cows= x

    Total no.of legs=4x

    Total no.of heads of cows= x

    let the no.of hens=y

    Total no.of legs of hens= 2y

    Total no.of legs=y

    Therefor, Total no.of heads= x+y

    Total no.of legs=4x+2y

    Given no.of legs are 14 more than twice the no.of heads

    4x+2y=14+2(x+y)

    4x+2y=14 +2x+2y

    2x=14

    x=14/2

    x=7//-
