Sum of divisors = 91.
Sum of 24's divisors: 60.
A perfect number equals the sum of its proper divisors. A deficient number is greater than the sum of its proper divisors. An abundant number is less than the sum of its proper divisors. Proper divisors of a number do not include the number itself.
The sum is 195.

A perfect number is the sum of its divisors; for example 6 is a perfect number because the sum of its divisors is 6 (1 + 2 + 3). The sum of the divisors of 8 is 7 (1 + 2 + 4), so 8 is not a perfect number.
Because the sum of its proper divisors is greater than 36.
No, 36 is not a perfect number. A perfect number is defined as a positive integer that is equal to the sum of its proper divisors (excluding itself). For 36, the proper divisors are 1, 2, 3, 4, 6, 9, and 12, which sum to 37, not 36. The smallest perfect number is 6.

Sum of divisors of 130 = 252.
Sum of 24's divisors: 60.
Sum of 150's divisors = 372.
The sum of its proper divisors 1, 2, 3, 4, 6, 9, 12, 18 is greater than 36.
