Answer 1

Answer:

53

Step-by-step explanation:

total = T = 150

Accounts = A = 45

Economics= E = 30

Maths = 50

accounts and maths= 30

maths and economics= 32

accounts and economics= 35

passed in all = 25

passed in none subject= none = ?

as such given data is not practically possible as number of students passing in economics are mentioned less than economics intersection with account or maths.

anyway solving data

150 = 45+30+50-30-32-35+25 + none

none = 97

passed in at least 1 subject= total - passed in none

=150-97

= 53

53 students passed at least in anyone of the subjects:
