5 women can complete a work in 8 days, while 8 children take 10 days to complete the same work. How many days will 2 women and 4 children take to complete the work?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 10
Given that,
5 women can complete a work in 8 days, while 8 children take 10 days to complete the same work
5 women × 8 days = 8 children × 10 days
women/children = 2/1
Let, total work = 8 × 10 = 80
According to the question,
(2 women + 4 children) × d = 80
(2 × 2 + 4 × 1) × d = 80
d = 80/8 = 10 days
