Answer:
Mr body took 9 blue pills
Step-by-step explanation:
Total number of pills consumed = 17
Number of blue pills, b = 11
Number of blue pills, b = g + 3
So that,
b = g + 3
11 = g + 3
g = 8
Total number of pills recommended = b + g
                              = 11 + 8
                              = 19
Total number of pills consumed = 17
Thus,
Number of blue pills consumed = 17 - 8
                           = 9
Therefore, Mr body took 9 blue pills.
