Question
10 girls can finish a task in 8 days, while 5 women can
finish the same task in 4 days. In how many days will 4 girls and 1 woman together finish the task?Solution
10G × 8 = 5W × 4 where G = girls and W = women
Or, 1W = 4G
Therefore, 4G + 1W = 4G + 4G = 8G
Therefore, 10 girls can complete the work in 8 days
So, 8 girls will complete in 10 days .
