  Here are the steps

  10) NaOH + HCl ----> NaCl + H2O

  Amount of HCl = 14.40/1000 x 0.7 = 0.01008 mol

  1mol of HCl ----> 1 mol of NaOH

  0.01008mol of HCl ----> 0.01008mol of NaOH

  Concentration of NaOH = 0.01008 / (20/1000) = 0.504mol / dm3

  Concentration in g/dm3 = 0.504 x (23+16+1) = 20.16g/dm3

  Did I do anything wrong? The answer is 13.9g/dm3

  Your answer is fine. The question is screwed up.
