hey I'm here with your answer:-
solution:-
In 30 days steel manufactured = 240 tonnes
Now, 60 more tonnes of steel is to be manufactured in that month.
So,
240+60 = 300 Tonnes of steel to be manufactured in the month.
Therefore,
More steel manufactured, less days the material will last.
This is an inverse proportion.
240 : 300 : : 30 : x
300x = 240*30
x = 7200/300
x = 24
So, the material will last for 24 days.
