Solution
To answer this question, we first need to understand the distribution of laptop users among the three companies: SONY, HP, and TOSHIBA.
From the information given, we know that:
- Total users = 200
- SONY users = 160
- HP users = 100
- TOSHIBA users = 90
- Users of all three = 20
- Users of SONY only = 40
We are asked to find the number of users who use only TOSHIBA and HP.
First, let's find the number of users who use more than one brand.
We subtract the users of all three brands and the users of SONY only from the total SONY users:
SONY users (more than one brand) = Total SONY users - Users of all three - SONY only users = 160 - 20 - 40 = 100
These 100 users are the ones who use SONY and at least one of the other two brands.
Next, we subtract this number from the total HP and TOSHIBA users to find the users who use only HP or TOSHIBA:
HP only users = Total HP users - SONY users (more than one brand) - Users of all three = 100 - 100 - 20 = -20
TOSHIBA only users = Total TOSHIBA users - SONY users (more than one brand) - Users of all three = 90 - 100 - 20 = -30
The negative numbers indicate that there's an error in our calculations. The number of users who use only TOSHIBA and HP cannot be determined from the information given in the question.
