Question

A fort has provisions for 420 soldiers for 70 days. After 10 days 210 more

Answer 1

Can you please make my answer brainliest please,

No. of soldiers=420

If each one have provisions for 70 days,

then, total provisions available=no. of soldiers*provisions each soldier have

=> total provisions available=420*70=29400units

now,until 10 days,

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

                                         =420*10=4200units

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

                                =29400-4200=25200units

now,after 10 days 210 more soldiers joined,

Now,

Total soldiers=420+210=630

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

                                                                  =25200/630

                                                                  =40days

Total no. of days they will sustain=40+10=50 days (as 10 days already passed away)
