Question

A={1,2,3,4,5,6,7,8,9},
B={2,4,6,8}
C={1,3,5,7,8}
If P={Factor of 36} and Q={Factors of AB} then find `n(P cap Q)`
A. 6
B. 5
C. 7
D. 8

Answer 1

Correct Answer - A
P== {1, 2, 3, 4, 6, 9, 12, 18, 36}
Q ={ 1, 2, 3, 4, 6, 8, 12, 16, 24, 48}
`P cap Q={J, 2, 3, 4, 6, 12}`
`therefore n(P cap Q)=6`
Hence , the correct option is (a).
