mamta garkoti  (9 years ago) Best Solution

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

sundeep gullapudi  (9 years ago)

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

Deep Marvania  (9 years ago)

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

rajoju.pushpa  (9 years ago)

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

Is this solution Helpfull? Yes (1) | No

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

Is this solution Helpfull? Yes (1) | No   

mohit tuteja  (9 years ago)

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

Is this solution Helpfull? Yes (1) | No
