Given :

Total musicians = 64

5/8 of musicians are guitarists

So, Number of guitarist = 5/8 × 64

= 40

Ratio of guitarist playing jazz solo to total guitarist = 1 : 4

Let the common factor of ratio be x

Then, x : 4x

Number of guitarist playing jazz solo, x = 40/4

= 10

So, Number of guitarist playing classical solo = 40 - 10

= 30

 

Hence, 30 guitarist play classical solos in the contest.
