Answer:
Step-by-step explanation:
Before solving the problem, we need to understand the basic concepts to solve the problem.
What is a composite number?
A composite number is a number which has factors other than 1 and itself. In other words a composite number is a number which is not a prime number.
Hence from this we need to find the first 5 composite numbers.
1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10
From this we can give up 1 , 2 , 3 , 5 , 7 as they are prime numbers.
then the composite numbers are 4 , 6 , 8 , 9 , 10
Adding these 5 numbers we get 4 + 6 + 8 + 9 + 10 = 37
