Total of 4 games = 120*4 = 480

1) 480+80/7 = 560/7 = 80 (yes)
2) 480+110/7 = 590/7 = 84.28 (No)
3) 480+185/7 = 665/7 = 95 (yes)
1&3 are correct.
Answer is E

(x1+....+x4)/4=120
X1+...+x4=480
(X1+...+x4 +x5)/5=7a
480/5+x5/5 =7a
96+x5/5= 7a
When x=80, 112/7=16
when x= 110, (96+22)/7=118/7 X
when x= 185, (96+ 37)/7=133/7 = 19

Answer is E

average of 4games=120
therefore total score of 4 games=480
option 1- 80
480+80=560
average of 5 games is 560/5=112. 112 is a multiple of 7 option 1 correct
option 2- 480+110=590/5=118.118 is not a multiple of 7 option 2 not correct
option 3-480+185=665/5=133.133 is a multiple of 7
