Direction (Qs.1 to 5): Read the following information carefully and answer the related questions.
Following table represents the data regarding number of students in five schools A, B, C, D and E in different classes.
1➤ There are 186 students in class 7 from all schools together and 195 students in class 10 from all schools together. Find the sum of students of class 7 and class 10 from school A and C together if students in class 10 from school A are 24 more than students from school E in same class.
(1) 128
(2) 132
(3) 146
(4) 152
(5) 160
In class 7:
Total students = 186
Students in school C = 186 - (35 + 41 + 39 + 42) = 29
In class 10:
Total students = 195
Let ‘n’ is number of students in school E.
Students in school A = 24 + n
195 = 24 + n + 47 + 44 + 40 + n
n = 20
n + 24 = 20 + 24 = 44
Students of class 7 and class 10 from school A and C = 35 + 29 + 44 + 44 = 152
2➤ Students from school A in class 6, 7 and 8 together are approximately what percent of students from school D in same class if sum of students of class 6 and class 8 in school D is 77?
(1) 88%
(2) 92%
(3) 99%
(4) 101%
(5) 107%
3➤ In school C, if there are 40%, 25% and 75% girls in class 6, class 8 and class 10 respectively, find the total number of boys in same class in school C.
(1) 41
(2) 53
(3) 65
(4) 69
(5) 74
4➤ What is the ratio of total students in school D to total students in school E if sum of students of 6th and 9th class in school D is 101 and sum of students of 8th and 10th class in school E is 9 less than the sum of students of same class in school D?
(1) 11 : 23
(2) 23 : 11
(3) 52 : 47
(4) 47 : 52
(5) 29 : 31
Total students in school D = 39 + 28 + 40 + 101 = 208
Sum of students of 8th and 10th class in school E = 28 + 40 - 9 = 59
Total students in school E = 46 + 42 + 59 + 41 = 188
Ratio = 208 : 188 = 52 : 47
5➤ If number of students in class 7 of school C is the average of total students of class 6th of school A and class 8th of school D Then Find the sum of students in 6th and 7th class from school A and C together?
(1) 135
(2) 142
(3) 159
(4) 164
(5) 167
