On a certain island, 5% of the 10000 inhabitants are one-legged and half of the others go barefooted. What is the least number of Shoes needed in the island?

• 10000
  one-legged =5% of 10000=500
  remaining=10000-500=9500
  barefooted=9500/2=4750
  remaining people= 9500-4750=4750
  hence required number of shoes= 4750*2+500*1=10000

• 5% of 10000 = 500 one legged
  9500 / 2 = 4750 bare foot
  minium no of shoes = 4750*2 + 500*1 = 10000

• 5% of 10000=500
  and half of remaining,so 9500/2=4750
  so total shoes required is 4750+250=5000 shoes

• one legged persons=(5x10000)/100=500
  therefore others=10000-500=9500
  half of 9500=4750
  now 10000-4750=5250
  two legged persons are 5250-500=4750
  total no of shoes=4750x2+500x1=10000

• 10000
  one-legged=5% of 10,000=> 500
  remaining=10,000-500=9500
  barefooted=half of remaining=(9500/2)=4750
  shoes are required for 4750 people=> 4750 pair of shoes=> 4750.2=9500
  one-legged people need single shoe=>500 shoes
  therefore, total no. of shoes required= 9500+500=10,000

• ans is 10,000.
  5% of 10000 is 500.
  500 are one-legged, so 500 shoes
  1/2 of remaining 9500=4750 are barefooted.
  now remaining 4750 needs 9500 shoes + 500(one- legged)=10,000

• 500are one legged
  and remaining 9500 are two legged
  out of these 9500 half i.e 4725 are barefooted
  Shoes required=2*4750+500=10000

  where they are one legged so we need shoes for one leg=500/2=250
  rest are bare footed ,no need of shoes for them.
  ans=250 shoes

• 72^21
  consider 2^21
  2^1=2 2^5=2
  2^2=4 2^6=4
  2^3=8 2^7=8
  2^4=6 2^8=6
  the sequence will repeat after every 4 values
  21/4 rem 1 that is 2^1=2=ans
