What is the total number of those who can play violin alone or flute alone? [2014-II]

Correct Answer: (b) 44
Solution:

a + b + c + d + e + f + g = 120                    g = (5 × 120) / 100 = 6

g = 6                                                          ...(1)
c + b + e = 30                                          ...(2)
a = 40                                                       ...(3)
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
