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
