Population of a colony of ants is increasing by 20% per day. If the population on Monday was 3000, on which day of that week the population would be 5184 ?

• Thursday
  
  
  5184 = 3000*(1+20/100)^n where n is number of days taken to reach 5184.
  (6/5)^n= 5184/3000=216/126= (6/5)^3
  SO n=3
  on Tuesday , population will be 3000*6/5
  on Wednesday , population will be 3000*(6/5)^2
  on Thursday , population will be 3000*(6/5)^3 = 5184

• Thursday.
  
  Monday - 3000, Tuesday = 3000+(3000*.20)= 3600
  
  wednesday = 3600+(3600*.20) = 4320
  
  Thursday = 4320+(4320*.20) = 5184

• monday
  population=3000
  
  tuesday
  population=3000 + 3000*20/100=3000+600=3600
  Wednesday
  population=3600 + 3600*20/100=3600+720=4320
  
  thursday
  population=4320+4320*20/100=4320+864=5184
  
  so that day is thursday

• on thurday the population will be 5184.
  given on monday population 3000
  tuesday 3000(1+ 20/100)=3600
  wednesday 3600(1+ 20/100)=4320
  thursday 4320(1+ 20/100)=5184.

• on monday the population is 3000, and 20% of 3000 is 600
  on tuesday the population is 3600(3000+600) and 20% of 3600 is 720
  on wednesday the population is 4320(3600+720) and 20% of 4320 is 864
  on thursday the population is 5184(4320+864).
  so the answer is thursday.

• Thursday as Monday is 3000 ,20% of 3000 is 600 so Tuesday is 3600,same 20% of 3600 is 900 so Wednesday population is 4500 and Thursday it will reach 5184

• Ans is thursday
  as
  on Monday population was 3000 and increase by 20% every day
  so on Tuesday it become 3000+20/100*3000=3600
  Wednesday 3600+20/100*3600=4320
  and on Thursday it become 5184

• Thursday
  
  on monday population is 3000
  
  now 20% is 1/5 calculate 1/5*3000=600 so on tuesday, population will be 3000+600=3600
  
  now 1/5*3600=720, so on wednesday, population will be 3600+720=4320
  
  1/5*4320=864 so thursday's population will be 4320+864=5184

• thursday
  Monday - 3000, Tuesday = 3000+(3000*.20)= 3600
  
  wednesday = 3600+(3600*.20) = 4320
  
  Thursday = 4320+(4320*.20) = 5184
