george'son can do a work in x days

george can do in x/5 days and also do 40 day earlier

x-x/5=40
4x/5=40
x=50
so george'son can do work in 50 days,and george can do in 10 days
now if they work together
1/50+1/10
60/500
so if they both work together they will do the work in 25/3 days(ans)

ans:
work ratio btwn gorge and his son is 5:1
so the ratio of time to complete total work is gorge:son=1:5
nw let gorge complte the work in y days
so as said in qustn son will complete it in (y+40)days
so y:(y+40)=1:5
y=10
so gorge will cmplt 10dys and son in 50 dys
so their combo 1hr work is 1/10+1/50=6/50
so they will cmplt the work to2thr in 50/6dys
ans is 50/6dys !!

If George takes x days to complete the work, his son takes 5x days.(since he is 5 times efficient than his son)
So, 5x-x=40
=>4x=40
=>x=10 days
George takes 10 days, so in one day he completes 1/10th of the work
his son takes 5x days=50 days,so in one day he completes 1/50th of the work
If both work together, work done in 1 day=1/10+1/50=6/50=3/25
So, no. of days to complete the work=25/3

Lets assume george does the work in x days,
then his son will do it in 5x days.

Now 5x-x=40 => 4x=40 => x=10

So 5x= 50(Son's days to complete the work) and x = 10 (George's days to complete the work).

When taking LCM,its 50 which gives George's one day work is 5, and George son's one day work is 1

therefore 50/6 => 25/3
