Question

125 pupil have food sufficient for 18days if 25 more people join them how long will the food last now please solve briefly

Answer 1

$\textbf{Answer}$

125 people have sufficient food for 18 days.

Suppose every person eats x amount of food every day.

=> Total amount of food eaten by 125 pepole in 18 days = 125 × 18 × x


Now 25 more people join.

So total number of people now is 150.

Suppose 150 people take y days to finish total food.

Since the amount of food eaten in both situations is same,

=> y = (125 × 18 × x) ÷ (150 × x)

=> y = 2250 ÷ 150

=> y = 15

So if 25 more people join,they will take just 15 days to finish the food.

Answer 2

♧ $\textbf{Given that ,}$

□ $\textbf{125 people}$ have sufficient food for = 18 days.

□ $\textbf{125 people = 18 days}$

□ 25 people join more in them.
So , the total people = 125 + 25
=> $\textbf{150 people.}$

♧ Let's suppose the food will continue => $\textbf{" x " days}$

□ 150 people = " x " days

♧ Since the number of $\textbf{soldiers increases}$ and the $\textbf{ days decreases.}$

According to the question ,

=> 125 × 18 = 150 * x

=> 2550 = 150x

=> x = 2550 / 150

=> x = 15

♧ Hence , after joining $\textbf{25 more people}$ in $\textbf{125 people}$ the the will be sufficient for $\textbf{15 days.}$
