Answer / jagjeet
Answer is 12 because
AUB means total students who speak Hindi and Kannada
which are 40-8 = 32
A= 24
B= 20
so we need to find A intersection B mean to say who are
common between them.
As per formula:
AUB = A+B-( A intersection B)
32 = 24+20-( A intersection B)
( A intersection B) = 44-32 => 12 ANS.
