Dear Student,
★ Answer :
Total consumption altogether: 800 man-days
________________________
★ Explanation :
⇒ In a ship there were stored food for 50 sailors for 16 days.
⇒ After 10 days 10 more soldiers joined them.
Q. How many days the remaining food last?
→ 50 × 16 = 800 man-days of food
Q. Find how many man-days of food available?
→ Let d = remaining days of food available, with the additional men added
⇒ 50 (d+10) + 10 d = 800
⇒ 50 d + 500 + 10 d = 800
⇒ 50 d + 10 d = 800 - 500
⇒ 60 d = 300
⇒ d = 300/60
⇒ d = 5 days
Check this,
★ Original group consumed 50(10+5) = 750 man-days of food
★ Additional 10 men consumed : 10 × 5 = 50 man-days
