Given below is a list of months and a corresponding code for each
▪ January: 7110 ▪ February: 826 ▪ March: 5313 ▪ April: 541 ▪ May: 3513 ▪ June: 4610 ▪ July: 4710
Observe carefully and decipher the code and find out how it is given, use the same rule to identify the code for August, September, November and December?

Decoding the code :
- The first digit gives the number of letters in the name of month.
- The second digit gives the number of month of the year it is.
- The remaining last digit(s) gives the number which the first letter of the month corresponds in the alphabetical order.
August : 681
September : 9919
October : 71015
November : 81114
December : 8124
January = 7110
February = 826
March = 5313
April = 541
May = 3513
June = 4610
July = 4710
Here some codes are in the form abc while the others are in the form abcd.
First I'm considering the second digit from left of each code.
January = 7110
February = 826
March = 5313
April = 541
May = 3513
June = 4610
July = 4710
January = 1
February = 2
March = 3
April = 4
May = 5
June = 6
July = 7
Here each code represents the position number of the months, so if we represent the code of August, September, October, November and December as abc, we will get,
August = a8c
September = a9c
October = a10c
November = a11c
December = a12c
Here b is replaced by the position numbers.
Now I'm considering the first digit from left of each code.
January = 7110
February = 826
March = 5313
April = 541
May = 3513
June = 4610
July = 4710
January = 7
February = 8
March = 5
April = 5
May = 3
June = 4
July = 4
These imply the no. of letters in each word of months. So, in the form abc, we write,
August = 68c
September = 99c
October = 710c
November = 811c
December = 812c
Now I'm considering the third and the rest digits from left of the code taken at one time (means taking cd from abcd.)
January = 7110
February = 826
March = 5313
April = 541
May = 3513
June = 4610
July = 4710
January = 10
February = 6
March = 13
April = 1
May = 13
June = 10
July = 10
These imply the position number of the first letter of each word of months in alphabet!
So in the form of abc, we can finally write,
