Step-by-step explanation:
Answer:
The material will be used for 24 days.
Step-by-step explanation:
Given that:
Materials made in a month = 240 tonnes
More materials to be made = 60 tonnes
Total material to be made = 240+60 = 300 tonnes
Days in a month = 30 days
Materials : Days
240 : 30
300 : x
As the production is increasing, the material will be used before 30 days.
This is an inverse proportion.
Using cross multiplication;
300*x = 240*30
300x = 7200
Dividing both sides by 300
Hence,
The material will be used for 24 days.
