If it took eight men ten hours to build a wall how long would it take four men to build it About the author Alaia
Let the time taken by four men by x hrs. No of people 8 4 Time taken 10 x Note that less the no. of people, the more would be the time taken. Therefore, this is a case of inverse proportion. So, [tex]8 \times 10= 4\times x \\ \frac{8 \times 10}{4} = x \\ 20 = x[/tex] Thus, the time taken to build the wall by 4 men is 20 hours. [tex] \color{yellow}{hope \: it \: helps \: !!}[/tex] Reply
