(1) The remainder when q is divided by 5 is 4.
(2) The tens digit of 2(5q + 1.5) is 9. (1) The units digit of \(q\) could be 4 or 9. Insufficient. (2) \(2(5q+1.5)=10q+3\). Note that the tens digit of \(10q+3\) is the units digit of \(q\). Hence, the units digit of \(q\) is 9. Sufficient. The answer is B.

(1) The remainder when q is divided by 5 is 4.
(2) The tens digit of 2(5q + 1.5) is 9. I'll go with option C. (1) Units digit can be 4 or 9. Hence not sufficient. (2) Tens digit of 10q+3 is 9. So 10th digit of 10q can be 8 or 9, likewise the unit's digit of q. Hence not sufficient. Example XXXX89 + 3 = XXXXX92. XXXXX90 + 3 = XXXXX93. Combining (1) and (2)  Unit's digit is 9 Cheers!

Okay I realized I made a blunder. (2) Tens digit of 10q+3 is 9. So 10th digit of 10q can be 8 or 9.  The last digit of 10q will always be 0. So only 9 is possible. Hence B alone is sufficient. Cheers!
