The repair department of the bycicle shop repairs three things: flat tires, bent handlebars and ripped seats. today in the repair department, 25% of the bikes had flat tires only, 5% had bent handlebars only, and 10% had ripped seats only. just 1/12th of the bikes had all three repairs to do: flat tires, bent handlebars and ripped seats. no bikes were completely fixed and there are a total of 101 repairs to be made. how many bikes are in the repair department? how many bikes need two repairs? if less than half of all the bikes have a ripped seat, what is the range of bikes that need both the tires and handlebars repaired without needing to fix the seat?
