Question

If the fourth proportional of x, 3 and 4 is equal to the thired proportional of 3 and 6 then, what is the value of x​

Answer 1

Step-by-step explanation:

Let fourth proportional of x , 3 and 4 is f.

x : 3 : : 4 : f

f.x=3.4 => f = 12/x

Now let 3rd proportional of 3 and 6 is t.

3 : 6 : : 6 : t

3.t = 6.6 => t =36/3= 12

Given :-

f = t

12/x = 12 => x = 12/12 = 1 ,
