Example 7: Given below is a pie chart showing the time spent by a group of 350 children in different

games. Observe it and answer the questions that follow.
less than 1 h
34% 1 h
30%
2 h
3 h
4 h
4%
16% 5 h
6%
10%
( 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) Calculate the central angle for the children who spend 3 or fewer hours in playing

games.
( d) Which is greater — the number of children who spend 2 hours or more per day or
the number of children who play for less than one hour?

Solution: (a) Percentage of children who spend at least one hour in playing games

= 16% + 30% + 34% + 10% + 4% = 94%

So, the number of children who spend at least one hour in playing games

94
= 94% of 350 = × 350 = 329
100
( b) Percentage of children who spend more than 2 hours in playing games
= 34% + 10% + 4% = 48%

So, the number of children who spend more than 2 hours in playing games

48
= 48% of 350 = × 350 = 168
100
( c) Percentage of children who spend 3 or fewer hours in playing games

= 6% + 16% + 30% + 34% = 86%
So, the central angle for the children who spend 3 or fewer hours in playing games

86
= 86% of 360° = × 360° = 309.6°
100
( d) Percentage of children who spend 2 hours or more per day

= 30% + 34% + 10% + 4% = 78%

Percentage of children who play for less than one hour = 6%

Since 78% > 6%.

Therefore, the number of children who spend 2 hours or more per day is greater
than the number of children who play for less than one hour.
