Out of a total of 120 musicians in a club, 5% can play all the three instruments, guitar, violin and flute. It so happens that the number of musicians who can play any two and only two of the above instruments is 30. The number of musicians who can play the guitar alone is 40. What is the total number of those who can play violin alone or flute alone?

[2014]

Solution:

So, a + b + c + e + d + f + g = 120 ...(4)

From (1), (2), (3) & (4)

40 + 30 + d + f + 6 = 120

d + f = 120 – 76

d + f = 44
