Question

In a camp there is enough rice for 300 persons for 42 days . How long will the rice last if 50 more persons join the camp ?

Answer 1

since the rice is enough for 300 persons for 42 days

$therefore \: the \: rice \: is \: enough \: for \: 1 \: person = 300 \times 42 \\ \\ = 12600 \: days$

$since \: 50 \: more \: persons \: join \: the \: camp \\ \\ therefore \: total \: number \: of \: persons \\ \\ = 300 + 50 = 350 \\ \\ therefore \: the \: rice \: is \: enough \: for \: 350 \: persons \\ \\ = \frac{12600}{350} \\ \\ = 36 \: days$

hope it helps.....
