The count of odd numbers that fit the description is 3
How to to determine the count of odd numbers that fit the description
From the question, we have the following parameters that can be used in our computation:
12, 19, 21, 3, 25, 18, 35, 20, 22, 21, 45, 46, 47, 49, 9, 50, 52, 54, 55, 56
From the above, we have
Odd numbers divided by 3 or 5 = 12, 21, 3, 18, 35, 21, 45, 9, 50, 54, 55
Odd numbers divided by 3 or 5 followed by an even number = 35, 45 and 9
Hence, there are 3 numbers in the series
Question
In a following series, how many such odd numbers are there that are divisible by 3 or 5, followed by odd numbers, and then followed by even numbers?
a) 3
b) 4
c) 5
d) 6
12, 19, 21, 3, 25, 18, 35, 20, 22, 21, 45, 46, 47, 49, 9, 50, 52, 54, 55, 56
