    x=35

    Step-by-step explanation:

    4:7::20:x

    let the fourth proportional number be x

    as we know to find the proportion we multiply extreme(1st and 4th)terms and middle terms to each other.

    Here,

    4x=140(following the above rule)

    x=140/4

    x=35

    hence ur answer is x=35
