The answers are both 72 / 2 and 8 / 3.
Given:
7 : 9 :: 8 : x :: 6 : 2
To Find:
The value of x ?
Solution:
7 : 9 = 8 : x = 6 : 2 , we know a : b = a / b.
7/9 = 8/x = 6/2 ....( 1 )
Taking 1st two fractions,
7/9 = 8/x
7 x = 72
x = 72/ 7 ....( 2 )
now,
Taking last two fractions from ( 1 ),
8/x = 6/2
6x = 16
x = 8/3 ....( 3 )
Hence required values of x are 72/2 & 8/3.
