(a+b)in one day 720/20=36 box
(b+c) in one day 720/24=30 box
(c+a)in one day 720/15=48
in 1 day all are 2(a+b+c)=36+30+48
a+b+c=114/2=57 box
so, a in one day=a+30=48 => a=27
b in one day=b+48=57 =>b=9
c in one day=c+36=57 =>c=21
a work for 4 day =27*4=108
b work for 8 day =9*8=72
c work for 8 day =21*8=168
so ,total no of boxes painted by them
108+72+168=348 boxes painted by them

2(A+B+C)'s work in a day=1/20+1/24+1/15
so A+B+C work=19/240
now A's work=19/240-1/24=9/240
so in 1 day a paints 9/240 *720 boxes=27 so in 4 days 27*4=108
similarly
b paints 72 n c paints 168
so total is 348 boxes
