Answers :
Directions (01-05):
Total students in a class is x
Students like only Tamil = 20%
Students like only English = 20%
Students like Tamil and Hindi but not English = 60% of 20
= 3/5 * 20 = 12%
Total students like only English and only Tamil = 20% + 20% = 40%
Students like English and Hindi but not Tamil = 25% of 40
= ¼ * 40 = 10%
Students like all the three languages = 5%
Remaining students = 100% – (20% + 20% + 12% + 10% + 5%)
= 100% – 67% = 33%
Students like only Hindi = 33% * 5/11 = 15%
Students like Tamil and English but not Hindi = 33% – 15% = 18%
Difference between the students like only Hindi and the students like Tamil and English but not Hindi = 18% – 15% = 3%
3% of total students = 36
Total students = 36/3 * 100 = 1200
1) Answer: C
Required percentage = 180/240 * 100
= ¾ * 100 = 75%
2) Answer: D
Required total = (20% + 20% + 15%) * 1200
= 55/100 * 1200
= 660
3) Answer: A
Required ratio = 144: 216
= 2: 3
4) Answer: B
Required total = (15% + 5% + 12% + 10%) * 1200
= 42/100 * 1200
= 504
5) Answer: C
Required total = (18% + 12% + 10% + 5%) of 1200
= 45/100 * 1200
= 540
