Question
A survey was conducted among 200 users of laptops of different companies. It was found that 160 use laptops of SONY, 100 use laptops of HP and 90 use laptops of TOSHIBA. 20 use laptops of all the three companies and each one uses laptops of at least one of the three companies.Q4. What is the minimum possible number of users, who uses only SONY ?Question 21Answera.45b.25c.30d.50
Solution
To find the minimum number of users who use only SONY laptops, we first need to subtract the number of users who use all three brands from the total number of SONY users. This gives us 160 - 20 = 140.
Next, we subtract the number of HP and TOSHIBA users from this number. However, since we want the minimum number of SONY-only users, we assume that all HP and TOSHIBA users also use SONY laptops (except for the 20 who use all three brands, which we've already accounted for). This gives us 140 - 100 - 90 = -50.
However, since we can't have a negative number of users, we conclude that the minimum number of SONY-only users is 0.
