Ration is availaable for 75 Students in a hostel for 20 day . how long will it last for the remaining students if 25 students left the hostel after 10 day
Answers
since:
If the number of student are 75 then after passing 10 days the ration is still present for more 10 day for the same 75 student.
We have to find out days for 50 student.
Let "x" be denote the number of days for 50 students.
Then
No of Students : Days
75 : 10
50 : x
Since:
"No of students are inversely proportional to Days"
Therefore
x / 10 = 75 / 50
⇒ x = (75 * 10) /50
⇒ x = (750) /50=25
⇒ x=25
So ration is enough for 25 days if 50 students remain after 10 days.
Answer:
Ration last for 15 more days
Step-by-step explanation:
Ration is available for 75 students on a hostel for 20days how long it last for the remaining students if 25 students left the hostel after 10days
Total Ration Available =75 * 20 = 1500 Student Days
Ration consumed in 10 Days by 75 Students = 75 * 10 = 750 Students Days
Ration available after 10 days = 1500 - 750 = 750 Students days
Students Left = 25
Remaining Students = 75 - 25 = 50 Students
Ration last for = Ration Available / Number of Students
=>Ration last for = 750/50
=> Ration last for 15 more days
