K is 3 digits and K's unit digit is not 0 means {1 through 9 }

When we add any number (1 through 9 } to 9, it will always generate a carry of 1.

A is saying that the tens digit of K+9 is 3. that means tens digit of K is 2 Suff

B is saying that the tens digit of K+4 is 2. If units digit is { 1 through 5} K+4 does not generate carry and the tens digit of k is 2. If K is 6 through 9, K+4 will generate a carry of 1 and tenth digit of k has to be 1. Insuff
