One day Rohit went to a park with his grandfather in the afternoon. He saw many peoples are

there doing different types of physical exercise. His grandfather told Rohit that there are 125 peoplein the park, out of which 12%jogging, 16% doing yoga and rest are walking.

To find :-

(i) How many people are walking?

(ii) How many people are doing yoga?

(iii) How many people are Jogging?

(iv) Find the percentage of people walking ?

Solution :-

Given that

Total number of people in the park = 125

Number of people who are jogging = 12% of the total people in the park

=> 12% of 125

=> 12% × 125

=> (12/100) × 125

=> (12×125)/100

=> 1500/100

=> 15

Number of people who are jogging = 15

Number of people who are doing yoga

= 16% of the total people in the park

=> 16% of 125

=> 16% × 125

=> (16/100) × 125

=> (16×125)/100

=> 2000/100

=> 20

Number of people who are doing yoga = 20

Total number of people who are jogging and doing yoga = 15+20 = 35

Number of remaining people = 125-35 = 90

Number of people who are walking in the park = 90

The percentage of people who are walking

= (Number if walking people/Total people )×100

=> (90/125)×100

=> (90×100)/125

=> 9000/125

=> 72%

The percentage of people who are walking in the park is 72%

Answer:-

i) Number of people who are walking in the park = 90

(ii) Number of people who are doing yoga in the park = 20

(iii) Number of people who are Jogging in the park = 15

(iv) The percentage of people walking in the park = 72%
