Question

20. In a camp there is enough provision for
500 students for 30 days. If 100 more
students join the camp, for how many
days will the provision last now.​

Answer 1

if

500 = 30

1 = 30÷ 500

600 = 30 ÷ 500 × 600

= 36

It will take 36 days

Answer 2

Answer:

GIVEN:

•Total Number of students, there's

enough provision for 500 students for

30 days.

TO FIND :

•If 100 more students join the camp,

then days of provision last now = ?

STEP-BY-STEP EXPLAINATION:

→ Let the number of days = X

→ Now, number of students in the camp

500 + 100 = 600

We, note that more is the number of

students, the less will be the number of

days the provision will last for.

So, it's the case of Inverse Variation

→$500 \times 30 = 600 \times x$

→$x = \frac{500 \times 300}{600}$

→$x = \frac{1500}{600}$

=> x = 25

Hence, Here the provision will last for 25 days.
