Answers
Answer:
Step-by-step explanation:
students days
100 20
25 more(100+25=125 X
X=20*100/125
x=16 Days
Given,
100 students in a hostel
Food provision for them is for 20 days
To find,
Provisions last if 25 more students join the group
Solution,
Let the consumption of 1 students in a day be 1 unit
consumption of 100 students in a day= (100 x 1)
= 100 units
Total amount of food in 20 days = (100 x 20)
= 2000 units
Now, number of students increase= 100 + 25
= 125 students
Therefore, number of days food will last = 2000/ 125
= 16 days
Hence, these provisions last if 25 more students join the group in 16 days.
