Detailed Solution

$HCl, {HNO}_{3} and H_{2} {SO}_{4}$ form azeotrope at $20 %, 68 % and 98 %$ respectively by mass of acid.

Therefore, HCI contains $\approx 20 / 100 = 1 / 5$

$\begin{aligned} {HNO}_{3} contains \approx 68 / 100 \approx 2 / 3 \\ H_{2} {SO}_{4} contains \approx 98 / 100 \approx 3 / 3 \end{aligned}$

Thus, ordinary strong solution of $HCl, {HNO}_{3} and H_{2} {SO}_{4}$

contains roughly $\frac{1}{5}$ , $\frac{2}{3}$ and $\frac{3}{3}$ fractions of pure acid and water respectively.
