In a class of 52 students, some speak Kannada, some speak English and some students speak both. If 30 students speak Kannada and 38 students speak English, how many students speak both languages?
A
18
B
16
C
20
D
15
Correct Option:
B
Explanation
Apply inclusion-exclusion. If 30 speak Kannada and 38 speak English, but there are only 52 students, then 30 + 38 - both = 52. Therefore, both = 68 - 52 = 16.
