Question

15. A garrison has food for 400 soldiers for
50 days. Some more soldiers join them and
the food lasts for 40 days only. How many
soldiers have joined them ?​

Answer 1

Answer:

50 days then number of soldiers = 400

1 day then number of soldiers = 400 × 50

40 days then number of soldiers = 20000/40 = 500 soldiers

numbers of soldiers joined = 500 - 400 = 100 soldiers
