Answer 1

Given :  only 80students in a school, out of them 48 students study mathematics and 44 students study commerce.

To find :  How many students study only mathematics

Solution :

Total Students  = 80

Study Mathematics  = 48  

Study Commerce  = 44  

Study math & Commerce both =  ?

Assuming each students study atleast one subject hence none = 0

Total = Mathematics  + Commerce   - Both

=> 80 = 48 + 44 - Both

=> Both  = 12

Study only Mathematics  =  Mathematics  - Both

= 48 - 12

= 36

36 Students Study only mathematics
