Question

A hostel had ration for 60days for 500students after 12 days 300more students join the hostel how long will the remaining ration last

Answer 1

Answer:

30 days

Step-by-step explanation:

Given:

Ration for 60 days for 500 students.

Total ration = 60 * 500 = 30000.

After 12 days :

Ration till 12 days = 12 * 500 = 6000.

Thus,

Remaining ration = 30000 - 6000

                            = 24000.

After 12 days 300 students joined.

Then,

Total students = 300 + 500 = 800.

Number of days ration last :

= 24000/800

= 30

Therefore,

Remaining ration last for 30 days.

Hope it helps!

$\green{\therefore{\text{Ration\:last\:long=30\:days}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given : }} \\ : \implies \text{Ration \: for \: 60 \: days = 500 \: students} \\ \\ : \implies \text{After \: 12 \: days \: 300 \: more \: students \: join} \\ \\ \red{ \underline \bold{To \: Find : }} \\ : \implies \text{Ration \: for \: 800 \: students = ?}$

• In the given question information given about ration of 500 student that is 60 days but after 12 days 300 joined the hostel then we have to find the how long the ration will be.

• So, first we calculate ration of 500 student for 60 days and then ration of 500 students for 12 days because on 12th days 300 more student joined.

• Then subtract the total ration for 12 days from total ration for 60 days.

• Then after that divide it from total students which are present after 12th day that is 800 students.

$: \implies \text{Ration \: for \: 60 \: days = 60 }\times 500 \\ \\ : \implies \text{Ration = 30000} \\ \\ \bold{Ration \: of \: 500 \: students \: for \: 12 \: days} \\ : \implies \text{Ration = 12 }\times 500 \\ \\ : \implies \text{Ration = 6000} \\ \\ \bold{Remaining\: ration : } \\ : \implies \text{Remaining = 30000 - 6000 }\\ \\ : \implies \text{Remaining = 24000} \\ \\ \bold{Number \: of \: days \: ration \: last \: long : } \\ : \implies \text{No.\: of \: days }= \frac{ \text{Remaining \: ration}}{ \text{Total \: no. \: of \: student}} \\ \\ : \implies \text{No. \: of \: days =} \frac{24000}{800} \\ \\ \green{ : \implies \text{No. \: of \: days = 30}}$
