Question

8 girls and 12 boys can finish work in 10 days while 6 girls and 8 boys can finish it in 14 days. Find the time taken by the one girl alone that by one boy alone to finish
the work​

Answer 1

Answer:

Step-by-step explanation:

No.of girls  No.of boys   No.of days

   8                   12                 14

   1                      1                   ?

Therefore,

no.of children in 1st case = 12+8 = 30

no.of children in 2nd case = 1+1 = 2

If 30 children take 14 days to complete the work 2 children will take more time to complete the work. So it is called inverse proportion.

Time taken by 2 children to complete the work =(30x14)/2=210
