In a survey, it is found that 30 people like apples, 45 people like oranges, and 20 people like both apples and oranges. How many people like only one fruit?
Answers
Answer:
35
Step-by-step explanation:
no.of people like apples = 30 (people contain both like only apple and like both apple and orange)
no.of people like orange = 45 (people contain both like only orange and like both orange and apple)
no.of people like both apples and oranges = 20
then, people like only one fruit = ( (30-20) + (45-20)) = 10+25 = 35
Given: Number of people who like apple= 30
Number of people who like oranges = 20
Number of people who like both = 45
To find: How many people like one fruit
Solution:
Let x be the number of people who like one fruit.
a + 20 = 30
a = 10
b + 20 = 45
b = 25
where, a represent people likinf only apple and b represenr people liking only orange.
Therefore, a + b
= 10 + 25
= 35
Hence, people liking only one fruit = 35
