Answer 1

Answer:

The number of days will food last for 25 people is 40 days .

Step-by-step explanation:

Given as :

The number of people = 20

Number of days the food have = 50 days

Again

The number of people = 20 + 5 = 25

Let The number of days will food last = d days

According to question

$\dfrac{men\times days}{work}$ = constant

So, $m_1$  × $d_1$  = $m_2$ × $d_2$

Or, 20 × 50 = 25 × d

i.e  d = $\dfrac{20\times 50}{25}$

∴   d = 40

So, The number of days will food last for 25 people= d  = 40 days

Hence, The number of days will food last for 25 people is 40 days . Answer
