(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.

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.
