let the average of 16 matches be x.

16x + 87 = Total of 17 matches.

on the other hand, (x+3)17 is also the total of 17 matches.

16x + 87 = ( x + 3) 17

16x + 87 = 17x + 51

x = 36.

Now we are looking for the average after 17 matches .

36 + 3 = 39.

let avg until 16th match = x
so
16x+87=17* ( x+3)
x = 36
x+3 ; 39
IMO B
