-
- ans is 8.33
let,one day work of g=1/y
one day work of hs sn=1/(y+40)
acc to ques 1/y=5/(y+10).......y=10
then 1/10 + 1/50=3/25
than total days to complete work together=25/3=8.33 days

- g=5*son
g-40=son
so,5*son-40=son
so,son's age=10
g's age=5*10=50
1day work of g=(1/50)
1 day work of son=(1/10)
together they do (1/50+1/10) work in 1 day
so,finally work is 500/60=8.33 - 11 years agoHelpfull: Yes(0) No(1)
- g=1/x-40,y=1/x
1/x-40=5/x,x=50
g=1/10+sn=1/50=6/50
so complete in 50/6
days=8.3

- here G works 5times faster than sn.
so if G takes tdays, then sn takes 5*t
so diff=4*t=40days
so t=10
G takes 10 while sn takes 50 days.
so if they work together, they would complt work in 8.33 days - 11 years agoHelpfull: Yes(0) No(0)
