Answer 2

$\sf\large\underline{Given:}$

In a camp,there is enough provision for 250 students for 30 days .If 50 more students join the camp, for how many days will the provision last now ?

$\sf\large\underline{To\: Find:}$

Number of days after joining the 50 more students the provision last?

$\sf\large\underline{Solution:}$

$\sf{\implies S_1\times\:D_1=S_2\times\:D_2}$

Here, S=student D=day's S²=250+50=300

$\sf{\implies 250\times\:30=300\times\:D_2}$

$\sf{\implies 7500=300\:D_2}$

$\sf{\implies D_2=25\:days}$

$\sf\large{Hence,}$

$\sf{\implies Provision\:for\: last=25\:days}$

$\sf{\underbrace{Answer-25\:days}}$
