Question

An army camp had food for 490 members of camp for 65 days. After 15 days, more people arrived and the remaining food lasted for 35 days. How many people joined the army camp.​

Answer 1

Step-by-step explanation:

Now as the soldiers increases food last for less days. ∴ It is inverse proportion. The proportion is (490 + x): 490 : : 50 : 35 Product of the extremes = Product of the means (490 + x) × 35 = 490 × 50 (490 + x) = (490×50)/35 x = 700 – 490 x = 210 ∴ 210 soldiers joined /camp-provisions-soldiers-after-more-soldiers-arrived-remaining-provisions-lasted-days
