A garrison had provision for a certain number of days. After 10 days, 1/5 of the men desert and it is found that the provisions will now last just as long as before. How long was that?
a. 15 b. 25 c. 35 d. 50
Ans: 50 days

• 1/5th of the men are satisfied for 10 days
  Implies 4/5 th of the men will be satisfied for 4*10 = 40 days.
  So, total days = 50 days

• If earlier food was there for x men for y days.
  Total quantity =xy
  After 10 days , qty = xy -10x
  
  As per given condition
  x*4/5 *y = xy-10x
  y(1-4/5) =10
  y=50 days

• X MEN - Y DAYS
  
  X/5 MEN - 10 DAYS ==> 4X/5 - 40 ----- (1)
  
  4X/5 MEN - (Y - 10) DAYS -------(2)
  
  (1) = (2) ===> (Y - 10) = 40
  
  Y = 50
