1st Digit: a= b*b
2nd Digit: b + c= 10
3rd Digit: d = b + 1
4th Digit: e + c = 14
Sum of all digits: a + b + c + d + e = 30
lets take 4th digit
e + c =14, so we can write it as
e + (10 -b) = 14
e - b = 4
e = 4 + b or e = b + 4
so here we go, sum of all digits
a + b + c + d + e = 30
b*b + 10 + b + 1 + b + 4 = 30
b*b + 2b + 15 = 30
b*b + 2b -15 = 0 (quadratic equations, 5 and -3 are the factors)
b*b + 5b - 3b - 15 = 0
b(b+5) -3(b + 5) = 0
b+5 = 0 or b - 3 = 0
b = -5 or b = 3 (avoid the -ve value)
so b = 3 and substitute in the original variables
1st Digit - a = b*b = 3*3 = 9
2nd Digit - b = 3
3rd Digit - b + c = 10, 3 + c = 10, c = 7
4th Digit - d = b + 1, d = 4
5th Digit - e + c = 14, e + 7 = 14, e = 7
so the 5 digit code is 93747
Postal Index Number (PIN) or Zip code is a 6 digit code. There are 8 PIN regions in India. Understanding how PIN Code works is simple if you understand the following:The first two digits of the PIN Code together indicates the sub region or one of the postal circles.The first three digits of the PIN Code together indicates a sorting / revenue district.The last three digits of the PIN Code refer to the delivery Post Office.

Goa is a state in India and the first three digits of its postal code are 403. The last three digits pertain to relevant villages or towns. Correct postal codes (commonly known as pin codes) can be obtained from google search. For example, the pin code for Panaji, the capital of Goa, is 403 001.
generally the four digit pin code is the last for digits of your phone number. like say my number was 203-555-4545. the pin would be 4545
