Question

Time spent by a student in a day is shown in the figure. Find how much time is spent in
(i) school
(ii) play ground
(iii) other activities

Answer 1

The ratio of the Angles shown in the pie diagram for playground: school: Other Activities $={30}^{\circ }:{105}^{\circ }:{225}^{\circ }$

Hence the above ratio could be simplified as $=2:7:15$

Let the student does those activities be in ratio $2x:7x:15x$

Then $2x+7x+15x=24$

$24x=24$

$x=1$

1. Hence the students spending time in School $=7x=7hrs$
2. Time spent on playground $=2x=2hrs$
3. Time spent on other Activities $=15x=15hrs$
