Let the number of calls in the 3rd evening=C
The number of calls in the first evening    =C - 5
The number of calls in the 2nd evening     =3C

 

C + C - 5 + 3C =95, solve for C
C = 20 calls in the 3rd eveningg
20 - 5 = 15 calls in the first evening
3 x 20 = 60 calls in the 2nd evening.
20 + 15 + 60 = 95 calls received in 3 evenings.
