8 : 9

Lets' assume quantity of steel and iron imported in 2018 were 3x And 2y respectively.

Lets' assume the quantities imported of steel and iron in 2020 A and A.

⇒ \(\frac{3y}{A}\) = \(\frac{4}{3}\)

⇒ \(\frac{y}{A}\) = \(\frac{4}{9}\)     ..(1.)

Ratio of the quantities imported of iron in 2018 and 2020 = 2y : A

⇒ 2 x 4 : 9   by (1.)

⇒ 8 : 9
