Explanation


Explanatory Answer

Method 1

            Here the total work to build a floor is considered as 1 unit.

Let the number of workers of Team A is x and number of workers of Team B is 2x.

 

Efficiency of worker of Team A = 1/100

Efficiency of worker of Team B = 1/200

 

From the Line Graph, we can conclude that the time to build third floor is 10 days.

Thus 5 workers of Team A and 10 workers of Team B built the third floor. Thus total number of workers is 15.

 

Method 2

 

Efficiency of worker of Team A = 1/100

Efficiency of worker of Team B = 1/200

Let the total units of work required to build the 3rd floor is 200 [ here we have considered LCM of time taken by workers of both the Teams i.e. 100 & 200].

Unit of work done by worker of Team A per day = 2

Unit of work done by worker of Team B per day = 1

Let the number of workers of Team A is x and number of workers of Team B is 2x.

From the Line Graph, we can conclude that the time to build third floor is 10 days.
