Solution:
Option(D) is correct

Let the total number of Linen shirts manufactured by all the given companies $= X$

Therefore, the number of Linen shirts manufactured by the companies P, Q, R and S is:

$\dfrac{X}{4}, \dfrac{X}{4}, \dfrac{X}{5}$ and $\dfrac{3X}{10}$ respectively.

Therefore, the total number of shirts manufactured by the companies P, Q, R and S is:

$\dfrac{5X}{6}, \dfrac{5X}{4}, \dfrac{4X}{3}$ and $\dfrac{6X}{5}$ respectively.

Let the profit per Khadi shirt and per Cotton shirt be 3y and 4y respectively.

Assume that the company R manufactures 400 shirts.

So, total profit generated by selling Khadi shirts will be:

$48 × 3y = 144y$

and the total profit generated by selling Cotton shirts will be:

$84 × 4y = 336y$

Required ratio is 7:3

So option D is correct choice.
