The time taken to build a house is inversely proportional to the numbe

1.	The time taken to build a house is inversely proportional to the number of builders. If there are 6 builders, it takes 80 days to complete the house. How many builders must be employed to build the house in just 16 days?
Answer» ACCORDING to me :- $16 \: days = \frac{16}{80} = \frac{1}{5}$ $time \: for \: 6 \: builders \: so \: the \: \\ number \: of \: builders \: required \: is$ $\frac{1}{ (\frac{1}{5} )} = 5 \: times$ $= 5 \times 6 = 30 \: \: builders$ [ Or ] $\frac{80}{16} \times 6 = 5 \times 6 = 30 \: builders$
