Let your ratio be 'x'
so that the time being spent converts to 1.x,3.x,4.x
now total hours in a day are 24 so a simple relation forms here
1.x+3.x+4.x=24
solving for x you get x=3
put back the value of x and you get number of hours spent in housekeeping=1.3=3hours
in sleeping=3.3=9hours
in studying=3.4=12hours
