The given circuit has two ideal diodes connected as shown in the figure below. The current flowing through the resistance $R_1$ will be:
Reverse-biased branch carries no current.
Current will not flow through $D_1$ as it is reverse biased. Current flows through the cell, $R_1$, $D_2$ and $R_3$.
$\therefore i = \frac{10}{2 + 2} = 2.5$ A
