# 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.

(a) How many children spend at least one hour in playing games?

(b) How many children spend more than 2 hours in playing games?

(c) How many children spend 3 or lesser hours in playing games?

(d) 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?

Answer :

(a) 6% children spend less 1 hour in playing games

Children who spend at least 2 hours = 100% – 6%

Children who spend at least 2 hours = 94%

⇒ No. of children spending atleast 2 hours = 329

(b) 34% children spend 3 hours in playing games

10% children spend 4 hours in playing games

4% children spend 5 hours in playing games

Total no. of children spending more than 2 hours = 34% + 10% + 4%

⇒ Total no. of children spending more than 2 hours = 48%

⇒ No. of children spending more than 2 hours = 168

(c) 6% children spend less than 1 hour in playing games

16% children spend 1 hour in playing games

30% children spend 2 hours in playing games

34% children spend 3 hours in playing games

Total no. of children spending 3 or lesser hours =

6% + 16% + 30% + 34%

⇒ Total no. of children spending 3 or lesser hours = 86%

⇒ No. of children spending 3 or lesser hours = 301

(d) No. of children who spent 2 hours or more = 30% + 34% + 10% + 4%

⇒ No. of children who spent 2 hours or more = 78%

And,

No. of children who spent less than 1 hour = 6%

Clearly,

No. of children who spent 2 hours or more is greater
