If 6 workers complete a certain task in 12 days, how many workers are needed to finish the same task in 4 days?

Let us take the Task to be Done as : T

Given : 6 Workers complete the task in 12 days

6 Workers do a Work of in One Day

If the Task is needed to be completed in 4 days :

Each Day work should be Done

We found that :

6 Workers do a Work of in One Day

6 × 3 Workers do a Work of in One Day

18 Workers do a Work of in One Day

18 Workers do a Work of T in 4 Days

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
