There is a certain relationship between two given numbers on one side of :: and one number is given on another side of :: while another number is to be found from the given alternatives, having same relationship with this number as the numbers of the given pair. Choose the best alternative.

22 : 8 :: 55 : ?

20

22 : 8 :: 55 : ?

22 = 8 × 3 - \(\frac{8}{4}\)

Following the same pattern,

55 = x × 3 - \(\frac{x}{4}\)

so, the value of x = 20
