1000 kg of mixed acid of composition 40% H₂SO4, 45% HNO3 and 15% H₂O is to be produced by strengthening waste acid of composition 30% H₂SO4, 36% HNO3 and 34% H₂O by weight. Concentrated sulphuric acid of strength 95% and concentrated nitric acid containing 80% acid are available for this purpose. How many kilograms of spent acid and concentrated acids are to be mixed together?
