Question

A bridge can be constructed by 1800 workers in 50 days. how many more such workers should be employed to complete the work in 30 days.​

Answer 1

Answer:

the number of workers required to build the bridge in 30 days = 3000

Step-by-step explanation:

     Given a bridge is constructed by 1800  workers  in 50 days

      the number of worker to complete the work in 30  = ?

    let the number of required workers = x

     number of days is decreased so the number of workers will be increased  

   ∴   the number of days and number of worker is in inversely proportion to each other    ⇒    1800 ×  50 = 30 × x

                                 x =  $\frac{ 1800 (50)}{30}$

                                 x =  3000

                   

 

         

Answer 2

Answer:

Given a bridge is constructed by 1800 workers in 50 days

the number of worker to complete the work in 30 = ?

let the number of required workers = x

number of days is decreased so the number of workers will be increased

∴ the number of days and number of worker is in inversely proportion to each other ⇒ 1800 × 50 = 30 × x

x = 1800 (50)}{30}

30

1800(50)

x = 3000
