Question: 2 women and 5 men can together finish an embroidery work in 4 days, while 3 women and 6 men can finish it in 3 days. Find the time taken by 1 woman alone to finish the work, and also that taken by 1 man alone.
Solution:
Let one woman takes x days to finish the work.
And one man takes y days to finish the work.
According to the question,
4(2y + 5x) = 1 xy
8y + 20x = xy...(1)
3(3y + 6x) = xy
9y + 18x = xy...(2)
8 x 36 + 20x = 36x
= x
x = 18
Hece, one woman takes 18 days and one man takes 36 days to finish the work.
Let one woman takes x days to finish the work.
And one man takes y days to finish the work.
According to the question,
4(2y + 5x) = 1 xy
8y + 20x = xy...(1)
3(3y + 6x) = xy
9y + 18x = xy...(2)
