Given : Students of different schools participated in various inter-school competitions,
rangoli 30 %
fancy dress, 10%
street play, 20%
declamation 15 %
puppet show 25%
75 persons participated in declamation contest
To Find : how many students participated overall
central angle representing participants of rangoli competition
number of participants in the activity with least participation
Solution:
rangoli 30 %
fancy dress, 10%
street play, 20%
declamation 15 %
puppet show 25%
Total 100 %
15 % = 75
Hence 100 % = (75/15) * 100 = 500
500 students participated overall
central angle representing participants of rangoli competition
= (30/100) 360
= 108°
number of participants in the activity with least participation
= 10 % fancy dress
= (10/100) 500
= 50
