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 Required percentage = 180/240 * 100

= ¾ * 100 = 75%

Required total = (20% + 20% + 15%) * 1200

= 55/100 * 1200

= 660

Required ratio = 144: 216

= 2: 3

Required total = (15% + 5% + 12% + 10%) * 1200

= 42/100 * 1200

= 504

Required total = (18% + 12% + 10% + 5%) of 1200

= 45/100 * 1200

= 540
