Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer: 91 - (3), 92 - (1), 93 - (1), 94 - (4), 95 - (1)

There are total 200 delegates.

• 45% of 200 speak English = 90

• No. of people speaking Latin is 10% of 200 less than no. of people speaking English = 90 - 20 =70

• Ratio of people speaking French to Latin = 5 : 7

        No. of people speaking Latin = 70

        Therefore, no. of people speaking French = 50

• English and French only - 15 people

        English and french only is 25% more than people speaking French and latin.

• 5% of 200 can speak all three languages = 10
• Only English and Latin = 5
• Since, total no. of people speaking French and Latin is 12 and amongst them  10 people speak all three languages.
• Therefore, only french and Latin = 2
• By the venn diagram formed we found that 32 people speak neither of the languages.
