A and B can paint 36 boxes in 1 day.
B and C can paint 30 boxes in 1 day.
C and A can paint 48 boxes in 1 day.
A+B+C together can paint (36+30+48)/2= 57 boxes in 1 day.
A+B+C together can paint 4*57=228 boxes in 4 days.
B+C together can paint 4*30=120 boxes in 4 days.

a+b+c= 19/240 ( 1 day work)
in 4 days they can paint (720*19/240)*4 = 228
after 4 days only b and c paints, they can paint (1/24 * 720)*4= 120
228+120 = 348

a+b=720/20=36boxes for one day....b+c=720/24=30boxes for1 day and c+a=720/15=48boxes for one day....by calculating these 3 equations we get a,b,c values i.e a=27,b=9,c=21..for one day..so here a worksfor 4 days so a=27*4=108,b=9*8=72and c=21*8=168..so a+b+c=108+72+168=348
