Directions(Q.6 to Q.10 ):
Data given about total number of students visited three towns, read the data carefully and answer the question:
There are 400 students visited three towns A,B and C. Out of total students 20% visited only town A, students visited only town B are 15% less than that of students visited only town A. 18% of total students visited only town C. Student visited town both A & B but not C are 8 less than students visited only town B, students visited town B & C but not A are half the students visited town A & B but not C. Students visited A & C but not B are half the sum of students visited only Town B and only town C together, remaining students visited all the three towns.
Find the total number of students visited at least two town?
Total students visited only town A = 400× =80
Total students visited only town B = 80×=68
Total students visited only town C = 400×=72
Total students visited town A & B but not C = 68 -8 = 60
Total students visited town B & C but not A = =30
Total students visited A & C but not B = = 70
Total students visited all the three towns
= 400 – (80 + 68 +72+60+30+70) = 20
Total number of students visited at least two towns
= 60 + 30 + 70 + 20 = 180
