Answer 1

Answer:

IT ISN'T POSSIBLE

Step-by-step explanation:

THERE IS NO SUCH NO. BY ADDING WITH 3,5,7 AND 10 WE GET PROPORTION

Answer 2

Answer:

3+x,5+x,7+x,10+x are the four numbers which is a form of proportion.

This can be represented as a:b::c:d=3+x:5+x::7+x:10+x

Simplifying it:

(3+x)(10+x)=(5+x)(7+x)

(3+x)(10+x)=(5+x)(7+x)

x2+13x+30=x2+12x+35

13x−12x=35−30

x=5

Note: The number is proportional when the ratio of the LHS of the proportional is equal to the RHS of the proportional
