Question

Помогите решить задачу по математике на английском!!!
On a desert island 1000 men can live for 30 days on the food they have.
After 16 days 400 more men arrive.
If they now eat half as much food as they did before, how long can they survive?
Give your answer to the nearest day

Answer 1

46 days

Because 1 day 1 man eats 1/30000

1 day 1000 men eat 1/30 of food

after 16 days 600 men have 16/30 parts of food

if they eat half food, so 600 men eat 600/60000 of food

14/30 ÷ 600/60000= 46,6 days
