In the following series, how many odd numbers are divisible by 3 or 5, followed by an odd number, and preceded by an even number?
12, 19, 21, 3, 25, 18, 35, 20, 22, 21, 45, 46, 48, 50, 52, 54, 55, 56
A
Nil
B
One
C
Two
D
Three
Correct Option:
B
Explanation
Look for an odd number divisible by 3 or 5, with an even number immediately before it and an odd number immediately after it. Only the sequence 22, 21, 45 fits: 21 is divisible by 3, 22 is even, and 45 is odd. So the count is 1.
