As we know in venn diagrams
Total = A+B - both,
we have both (musician and actor )= (19+10) - 24 = 5
thus musician but not actors is : (musician - both)
= 19-5 =14
ANSWER : B
Total = A+B - both,

Double Matrix method:
Actor Not actor
|------|------|Musician
| x |19-x | 19 Not musician
|------|------|
| 10-x | 0 |
---------------
10
x+(19-x)+ (10-x) = 24
29-x = 24
x= 5
19-5 = 14 ans
