A garrison of 3300 men has provisions for 32 days when supplied at the rate of 850 g per head. At the end of 7 days, a reinforcement arrives, and it is found that the provisions can last for 17 days more when supplied at the rate of 825 g per head. What is the strength of the reinforcement?
(a) 1700 (b) 1000 (c) 3000 (d) 2700

• 3300*32*.850=89760
  3300*7*850=19635
  89760-19635=70125
  
  x+3300*825*17=70125
  x=1700

• In every 3 yrs it will be 1.5 times
  
  there are 5 such sessions will come
  
  amount after 3 yrs is (2000)*(1.5)
  
  amount after 6 yrs is ((2000)*(1.5))*(1.5)
  
  amount after 9 yrs is (((2000)*(1.5))*(1.5))*1.5=2000*(1.5)^3
  
  amount after 18 yrs is 2000*(1.5)^6
  
  =2000*11.390625
  
  =22781.25
