Solution
The correct option is C 44
Out of 120 only 5% can play all the instruments.So, 6 musicians can play all three instruments.
Only 30 musicians can play any two or only two instruments and 40 can play guitar alone.
So the number of musicians who can play flute or violin alone would be 120−(30+40+6)=120−76=44.Hence, option C is correct.
Out of 120 only 5% can play all the instruments.
So, 6 musicians can play all three instruments.
Only 30 musicians can play any two or only two instruments and 40 can play guitar alone.
So the number of musicians who can play flute or violin alone would be 120−(30+40+6)=120−76=44.
Only 30 musicians can play any two or only two instruments and 40 can play guitar alone.
So the number of musicians who can play flute or violin alone would be 120−(30+40+6)=120−76=44.
Hence, option C is correct.
