A meter bridge setup is shown in the figure. It is used to determine an unknown resistance R using a given resistor of 15 \(\Omega\). The galvanometer (G) shows null deflection when tapping key is at 43 cm mark from end A. If the end correction for end A is 2 cm, then the determined value of R will be ____________ \(\Omega\).
