(b) Total number of musicians = 120

Number of musicians who can play all the three

instruments = 5% of 120 = 5/100 x 120 =6

Number of musicians who can play any two or only two of three instruments = 30

 Number of the musicians who can play the guitar alone = 40 

Now the number of musicians who can play violin alone or flute alone =Total number of musician – the number of musicians in all three categories = 120 – (30 + 40 + 6) = 120 – 76 = 44
