If 4 men and 6 women can complete a work in 8 days
4 men and 1 women can complete a work in=6* 8 days
1 men and 1 women can complete a work in=4*6* 8 days
1 men and 7 women can complete a work in=4*6*8/7 days
3 men and 7 women can complete a work in=4*6*8/(3*7) days
=64/7days
which is not 10 days as given in the question

Hi Shehina,
10 women's 1 day's work = 1/40 means they will take 40 days to complete a work
for example a man can do a work in 10 days means we will take his one day work as 1/10
like that one day work is 1/40 they should complete it in 40 days.
i think you understood..

Hi Bhuvi,
if A takes 10 days to complete a work means
A's one day work is 1/10
Same way 10 women's one day work is 1/40 means they will take 40 days to complete the work.
I think you got my point.
If you need some more help you can direcly write to my id

Have a nice day

hii,
can you pls explain
how comes
4x + 6y = 1/8 and 3x + 7y = 1/10
x = 11/400 , y = 1/400

hi all,
can you please explain
4x + 6y = 1/8 --(1)
3x + 7y = 1/10 --(2)
From (1) and (2) How it comes
x = 11/400 , y = 1/400

hi , first
4x + 6y = 1/8 --(1) ----> (1) * 30
3x + 7y = 1/10 --(2) ----> (2) * 32
hence
960x+1440y=30/8 (for some instance you forget about /8)
( or u can multiply this 8 and with the corresponding x an y values)
960x+2240y=32/10 (for some instance you forget about /10)
----------------
800y=1/400
y = 1/400
by substituting the value of y Eqn (1)
yo will get 4x+6/400=1/8
x=11/400

Hi CHAN,
Can u explain how that 960 x + 1440y = 30/8 came and 960x + 2240y = 32/10 ?.
