Answer:
30 persons will consume 48 kg of rice in 21 days
Step-by-step explanation:
Given:
42 persons consume 144 kg of rice in 45 days
Let the quantity of rice consumed by 1 person in 1 day be defined as "person-days"
=> 42 * 45 person-days will need 144 kg of rice
=> 1890 person-days will need 144 kg
=> 1 person in 1 day will need (144/1890) kg of rice
=> 1 kg of rice will last for (1890/144) days for 1 person
=> 48 kg of rice will last for 48*(1890/144) days for 1 person
=> 48 kg of rice will last for 630 days for 1 person
If there are 30 persons,
=> 48 kg of rice will last for (630/30) days
=> 48 kg of rice will last for 21 days
Answer: It will take 21 days for 30 persons to consume 48 kg of rice.
