Question

A hostel with 300 students has provisions for 45 days.After 10 days 150 membef joined .What is the provisiob days

Answer 1

Can you please make my answer brainliest please,

No. of students=300

If each one have provisions for 45 days

then, total provisions available=no. of students*provisions each student have

=> total provisions available=300*45=13500units

now,until 10 days,

The total provisions used=no. of students*no. of days

                                         =300*10=3000units

Now,left provisions=total provision-used provision in 10 days

                                =13500-3000=10500units

now,after 10 days 150 more students joined,

Now,

Total students=300+150=450

no. of days after joining they will sustain=left provisions/total no. of soldiers

                                                                  =10500/450

                                                                  =23 days 8 hours

Total no. of days they will sustain=23days 8hours+10days=33days 8hours (as 10 days already passed away)
