Question

12 men can build a wall in 5 days. 4 points How many days would be required to build the wall in just 2 days.​

Answer 1

Answer:

If the number of workers decreases, the time to taken built the wall increases in the same proportion. Clearly, number of workers varies inversely to the number of days.

So here

y

1

x

1

=

y

2

x

2

where

x

1

=36 workers y

1

=12 days

x

2

=16 workers and y

2

=? days

Substitute,

16

36

=

12

y

2

⇒ y

2

=

16

12×36

=27 days

Therefore 16 workers will build the same wall in 27 days.
