Solution:
Option(C) 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.

Assume that the total number of Linen shirts manufactured by all the companies is 100.

Therefore, the total number of Linen shirts manufactured by the companies P, Q, R and S is 25, 25, 20 and 30 respectively.

The following table lists down the number of shirts of each type of cloth manufactured by each of the companies, when the total number of Linen shirts manufactured is 100.

Therefore, for the number of shirts of each type of cloth to be an integer we need to convert all the fractional values in the table to integers.

In order to do so, we need to multiply the entries for P with 3, the entries for Q with 4, the entries for R with 3 and the entries for S with 5. So, if we multiply all the entries with the l.c.m of 3, 4, 3 and 5, that will do the needful.

Minimum possible number of shirts manufactured by all the companies:

$= (83.33 + 125 + 133.33 + 120) × (3 × 4 × 5)$

$= \textbf{27,700}$
