in a hostel there is enough food for 5 days for 20 students. After 1 day 5 students left the hostel .How long the remaining food will last now?

Total no. of students after joining 75 more =125+75=200

Now,

No. of days food will last for 125 students =16

No. of days food will last for 1 students =16×125

No. of days food will last for 125 students =  

200

16×125

=5×2=10 days

Step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the diameter is 16 cm. are you a teacher?
