(a) How many children spend at least one hour in playing games?
From the given pie chart,
Percentage of children who at least spend one hour in playing = 16 + 30 + 34 + 10 + 4
= 94 %
Number of children out of 350 who at least spend one hour in playing = (94/100) × 350
= 0.94 × 350
= 329 children
(b) How many children spend more than 2 hours in playing games?
From the given pie chart,
Percentage of children who spend 2 hours in playing = 34 + 10 + 4
= 48 %
Number of children out of 350 who at least spend one hour in playing = (48/100) × 350
= 0.48 × 350
= 168 children
(c) How many children spend 3 or lesser hours in playing games?
From the given pie chart,
Percentage of children who at least spend one hour in playing = 6 + 16 + 30 + 34
= 86 %
Number of children out of 350 who at least spend one hour in playing = (86/100) × 350
= 0.86 × 350
= 301 children
(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?
Number of children who spend 2 hours or more per day = 30 + 34 + 10 + 4 = 78%
= (78/100) × 350
= 0.78 × 350
= 273 children
Number of children who play for less than one hour = 6%
= (6/100) × 350
= 0.06 × 350
= 21 children
So, by comparing both it is clear that number of children who spend 2 hours or more per day is greater
