Question 60

The number of adults who come only to walk in a park every day is 140. 18% of the adults come only to accompany their children in the park. 54% of the adults come only to run in the park. What is the total number of adults who come to the park every day (if the adults come for no other activity other than for the given reasons)?

Solution

18% of the adults come only to accompany their children in the park. 54% of the adults come only to run in the park.

The number of adults who come only to walk in a park every day is 140.

number of adults who come only to walk in a park every day = (100-18-54)% = 140

(100-72)% = 140

28% = 140

1% = 5

Total number of adults who come to the park every day = 100% = $$100\times5$$

= 500
