Question

In a music band all except 4 are singers, all except 4 are guitarists, all except 4 are violinists. how many are there in the band?

Answer 1

In a music band all except 4 are singers, all except 4 are guitarists, all except 4 are violinists. The number of members in the band is 6

Step-by-step explanation:

Let there are X members in the band

Then

All except 4 are singers

i.e. number of singers = X-4

All except 4 are guitarists

i.e. number of guitarists = X-4

All except 4 are violinists

i.e. number of violinists = X-4

Therefore,

$X-4+X-4+X-4=X$

$\implies 3X-12=X$

$\implies 2X=12$

$\implies X=6$

Hope this helps.
