A single-phase, $4\:kVA, 200\: V/100\: V, 50\:Hz$ transformer with laminated CRGO steel core has rated no-load loss of $450\: W.$ When the high-voltage winding is excited with $160\: V,40\: Hz$ sinusoidal ac supply, the no-load losses are found to be $320\: W.$ When the high-voltage winding of the same transformer is supplied from a $100\: V, 25\: Hz$ sinusoidal ac source, the no-load losses will be _______  $W$ (rounded off to $2$ decimal places).
