40/x=100/190 40/x=100/190
(40/x)*x=(100/190)*x
40=0.526315789474*x
(0.56315789474) to get x
40/0.536315789474=x
76=x
x=76 now we have 190% of 76
The table in correct format is attached below.
Total number of runners = n = 724 + 103 = 827
Number of Runners who do not bike = x = 103
Percentage of runners who do not bike =

x 100%

x 100%
= 12.5%
Thus, 12.5% of Runners do not ride bike for exercise
