Question

in a camp there are 420kg of rice sufficient for 98 persons for 45 days the number of days tht 60kg of rice will last for 42 persons is_____​

Answer 1

Answer:

15 days

you first need to calculate the requirement of 1 person per day then multiply it by 42 and divide 60 by it

Answer 2

The number of days that 60kg of rice will last for 42 persons is 15 days.

As given:

Quantity of rice= 420kg

No of persons= 98

No of days= 45



So, for 98 persons in 45 days, rice required is 420kg

So, for 1 person in 45 days, rice required = 420/98 = 4.28 kg

Now, for 45 days, rice required for 1 person is 4.28 kg

So, for 1 day, rice required for 1 person is 4.28/45 kg



Now, for 1 person/day = 4.28/45 kg

So, for 42 persons/day= (4.28/45)*42 = 3.99 kg or 4kg

As we found, 4kg required for 1 day

So 60 kg will be required for 60/4 = 15 days

Therefore, the required answer is 15 days.
