It is given that
10ml of NaOH neutralizes 8ml Solution of HCl
\therefore 1 ml of NaOH neutralizes = \frac{8}{10} = \frac{4}{5} \ ml Solution of HCl
Therefore, 20 ml of NaOH will neutralise= \frac{4}{5}\times 20=16 \ ml solution of HCL

Therefore, 16 ml of HCl solution will be required to neutralize the 20 ml of NaOH.

The correct answer is (d)
