Question 12

100 perons had food provision for 24 days. If 20 persons left the place, the provision will last for
(a)30 days
$\left(b\right)\frac{96}{5}days$
(c)120 days
(d)40 days

Answer 1

$\because$ 100 persons had food provision for 24 days
$\therefore$ 1 person had food provision for $24\times 100$ i.e. 2400 days.
If 20 persons left the place, then remaining persons =(100 -20)=80
$\therefore$ 80 persons had food provision for$\frac{2400}{80}$ i.e. 30 days.
Hence, option (a) is correct.
