Detailed Solution

HCl, HNO₃ and H₂SO₄ form azeotrope at 20%, 68% and 98% respectively by mass of acid.
Therefore, HCI contains $\approx$ 20/100 = 1/5
HNO₃ contains $\approx$ 68/100 $\approx$ 2/3
H₂SO₄ contains $\approx$ 98/100 $\approx$ 3/3
Thus, ordinary strong solution of HCl, HNO₃ and H₂SO₄contains roughly 1/5,2/3 and 3/3 fractions of pure acid and water respectively.
