Solution :
Number of school A students = 140
Number of school B students = 70
Number of school C students = 105
Number of school D students = 35
Total students in the camp (T)
= 140+70+105+35
= 350
Participation of A = ( 140 )/350 × 100%
= ( 2/5 ) × 100%
= 2 × 20 %
= 40%
Participation of B = ( 70/350) × 100%
= ( 1/5 ) × 100%
= 20%
participation of C = ( 105/350 ) × 100%
= ( 15/50 ) × 100%
= 15 × 2%
= 30%
participation of D = ( 35/350 )×100%
= ( 1/10 ) × 100%
= 10%

Answer:
Sol : Total number of students in a camp = 140 + 70 + 105 + 35 = 350. Total number of students in school A = 140 percentage of school A = [140 / 350 ] x 100 = 40% Total number of students in school B = 70 percentage of school B = [70 / 350 ] x 100 = 20%. Total number of students in school C = 105 percentage of school C = [105 / 350 ] x 100 = 30% Total number of students in school D = 35 percentage of school D = [35 / 350 ] x 100 = 10%.
