What kind of math problem is has this "author" created - one that seems to promote THEFT?
Don't you think it's a lot better if this problem started out like this:
"Anil FORGOT the password for his ATM debit card. He knows that the password of the card is of four digits and one of the digits is an even number.
He also REMEMBERS punching three distinct digits which lie on either of the diagonals on the keypad........."
