let sunday= abcd; then a+b=cd;b=7;a=9; cd=16; so abcd=9716 reason second digit increases sequentially 1,2,3,4,5,6,7..from monday to sunday; first digit is greater than second digit; and first digit in each day is different from previous day; so it 9716
In that case : Corrected solution : My above solution needs slight modification: a= no of letters in lettes of word The ANSWER should be : a=6(SUNDAY);b=7(SEQUENCE(From MONDAY TO SUNDAY);THE FIRST DIGIT NEED NOT BE GREATER THAN SECOND); a+b=cd; cd=a+b=13 ; abcd=6713
let sunday= abcd; then a+b=cd;b=7;a=9; cd=16; so abcd=9716

The ANSWER should be :
a=6(SUNDAY);b=7(SEQUENCE(From MONDAY TO SUNDAY);THE FIRST DIGIT NEED NOT BE GREATER THAN SECOND); a+b=cd; cd=a+b=13 ;
abcd=6713
This is the right answer! Thanks for solving my riddle!
