Solution

Step1: Finding he job to be completed on $1$ day
The number of machines is inversely proportioned to the number of days
$60$ days $= 30$ machines
$1$ day $= 60 x 30 = 1800$ machines
Step2: Finding the job to be completed in $40$ days
$1$ day $= 1800$ machines
$40$ days $= 1800 \div 40 = 45$ machines
$∴ 45$ machines are needed to complete the job in $40$ days.
