Hi Vani,
"A perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself."
Lets try 6,
Divisors of 6 = 1 , 2 and 3
1+2+3 = 6 (Hence 6 is a perfect number).
Lets try 10,
Divisors of 10 = 1, 2 and 5
1+2+5 = 8 (since this is not equal to 10, 10 is not a perfect number).
