Molten steel is produced at a rate of 1275 kg/hr. This is distributed to 36% for extrusion, 10% for cold-rolling, 8% for hot-rolling and the rest for casting. The efficiencies of extrusion, casting and rolling (both hot and cold) are 95%, 99% and 90%, respectively, based on total weight of the products produced. If the required shape cast steel from the process is 978 kg/hr, how much scale-up is needed for the steel plant? Give your answer in terms of % increase in the production in one decimal place.
