Answer 1

here 40 kg is 30×8 units which is240 units for 10 members it will last for 240 ÷10 which is 24 days

Answer 2

If 2 guests stay with the family then 40 kg of rice will last for 24 days.

Given : 40 kg of rice lasts 30 days in a family of 8 persons.

To find : The number of days that 40kg rice will last after arrival of 2 guests.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the required number of days)

Here, we will be using general arithmetic method.

Number of persons in the family after arrival of 2 guests :

= 8 + 2

= 10

So,

For 8 persons 40kg rice lasts for = 30 days

For 1 person 40kg rice lasts for = (30×8) days

For 10 persons 40kg rice lasts for = (30×8)/10 = 24 days

(This will be considered as the final result.)

Hence, if 2 guests stay with the family then 40 kg of rice will last for 24 days.
