The singly reinforced concrete beam section shown in the figure (not drawn to the scale) is made of $M25$ grade concrete and $Fe500$ grade reinforcing steel. The total cross-sectional area of the tension steel is $942\:mm^2$.

As per Limit State Design IS $456:2000$, the design moment capacity (in $kN.m$, round off  to two decimal places) of the beam section, is  __________
