sir in question no.9 you taken wrong because they started work together for 4 days then A left ,Yes exactly because 1st 4 days they did work together so total 52 units done,than a left and b left after 2 days so B and C did work together 2 days total 14 units and remaining units is done by C = (192-52-14)=126, C do in days = 126/3 =42 days ! Thanks

You have calculated the days when C worked alone.But C has worked 4 days with A,B and next 2 days with B only,and rest alone so total days are 48 days.
Praveen, ur answer-42 would b right if question was- how many more days will C take to finish it ! But since question says that how many days will it(here it=work not C) take to complete so we have to calculate total no. of days taken to complete the work which is 42+6 =48
