Given below is a pie chart showing the time spend by a group of 350 children in different games. Observe it and answer the questions that follow:
- How many children spend at least one hour in playing games?
- How many children spend more than 2 hours in playing games?
- How many children spend 3 or lesser hours in playing games?
- Which is greater — number of children who spend 2 hours or more per day or number of children who play for less than one hour?
उत्तर
a. Number of children who spend atleast 1 hour in playing games i.e. the number of children playing 1 hour or more than 1 hour
= (Total number of children) – (Number of children spend less than 1 hour)
= 350 – 6% of 350
= `350 - 6/100 xx 350`
= 350 – 21
= 329
b. Number of children who spend more than 2 hours in playing games
= (34 + 10 + 4)% of the total number of students
= 48% of 350
= `48/100 xx 350`
= 168
c. Number of children who spend 3 or lesser hours in playing games
= (34 + 30 + 16 + 6)% of total number of students
= 86% of 350
= `86/100 xx 350`
= 301
d. Number of children who spend 2 hours or more per day in playing games
= (30 + 34 + 10 + 4)% of total number of students
= 78% of total number of students
Number of children who spend less than one hour = 6% of total number of students
Clearly, number of children who play for 2 hours or more per day is greater than the number of children who play for less than 1 hour.
