Answer:
2 people will take 90 days to complete the same house
Step-by-step explanation:
<u><em>Given:</em></u>
T1 = 30 days
P1 = 6
T2 = x
P2 = 2
This is an inverse proportion because if there are more people, less time will be taken to complete the house and vice versa.
<u><em>So, We'll write it in the order of :</em></u>
=> T1:T2 = P2:P1
=> 30:x = 2:6
<u><em>Writing in fraction form</em></u>
=>
<em>Cross Multiplying</em>
=> 2x = 180
<em>Dividing both sides by 2</em>
=> <u><em>x = 90 days</em></u>
So, <u><em>2 people will take 90 days to complete the same house</em></u>
