A mountain hiker is carrying a backpack, as he travels in the hills to climb new peaks. In his bag, he has the complete mountaineering kit and hit stuff. His kit is three kilograms and half a kit heavy. Along with that, his essential utilities are four kilograms minus one-fourth the weight of his kit. His food supplies account for two-fifth the weight of his kit and essential utilities. To add to that, his repair kit (consisting of various things to repair his mountaineering kit) is half a kg and one-fourth his repair kit heavy. His bag is barely one-fourth the weight of his repair kit. Calculate the total weight on his shoulders.
