Question

According to a survey, at least 70% of people like apples, at least 75% like bananas and at least 80% like cherries. What is the minimum percentage of people who like all three?

Answer 1

Answer:

Step-by-step explanation:  

1. people liking 70% apples
2. people liking 75% bananas
3. people liking 80% cherries

let take lcm then

• 70 = 2*5*7
• 75 = 3*5*5

• 80 = 2^{4}*5 then,

2*3*5*5*7*2*2*2 = 8400

due to percentage divide by 100 = 8400/100 = 84%

therefore 84% people like all fruits
