in a survey 2000 people were asked whether they read indiatoday or business times it was find that 1200 read india today 900 read business tines 400 read both find howmany read atleast one magazine and how many neither​

Answer 1

Answer:

1300 at least 1 magazine

300 neither

Step-by-step explanation:

1200-400 = 800

900 - 400 = 500

800 + 500 = 1300 + 400 = 1300

1300 +400 = 1700

2000 - 1700 = 300

Answer 2

Given:

Total number of people = 2000

Number of people that read India Today = 1200

Number of people that read Business Times = 900

Number of people that read both = 400

To find:

The number of people who read at least one magazine and who neither read anything.

Solution:

The number of people who read at least one magazine = Number of people that read India Today + Number of people that read Business Times - Number of people that read both

= 1200 + 900 - 400

= 2100 - 400

= 1700

The number of people who don't read anything will be = Total number of people - Number of people who read at least one magazine

= 2000 - 1700

= 300

Thus, the number of people who read at least one magazine is 1700 and the number of people who don't read anything is 300.
