Let n be the sample size in each sub groups
R_Bar be the mean of Ranges from all the subgroups.
Then the upper control limit of the R-Chart is
UCL = D4 × R_Bar
D4 can be calculated from the Control limit table for the corresponding 'n' given in the problem.
I am attaching the table which will help you
