Question

A guesthouse has enough food to feed 45 persons for four days. How long will the food last
if 15 more people came?

Answer 1

Answer:

x = $\frac{20}{3}$

Step-by-step explanation:

By the proportion of person and lasting food days is proportional

so,

let no. of days last = x

$\frac{45}{4} = \frac{60}{x}$

then,

$45x = 60 X 4$

x =  $\frac{60X4}{45}$

x =  $\frac{5 X 4} {3}$

x = $\frac{20}{3}$
