28. Out of 6000 apples in a row, every 3rd apple is damaged, every 4th apple is not ripened, every 10th apple is made by using chemicals and the rest are ready to eat. How many apples among 6000 are ready to eat?

• if every 3rd apple is damaged so with in 1-10 apple the damaged apple will be 3(1,6,9)
  every 4th apple not ripened so 2 apple(4,8) with in 1-10
  every 10th apple made by chemicals so only 10th apple also not ready to eat,so 1 apple with in 1-10,
  total not able to eat (3+2+1)=6 with in 10 apple
  the not able to eat apple will be (6000/10*6)=3600
  then the apple will be ready to eat is (6000-3600)=2400 ans.

• It may be the case when you will get common no. of apples in 3 groups.
  
  e.g. 12, it will be common in every third and fourth apple.
  
  Similarly,60th apple will be common in all 3 groups.
  
  So, 60 is the first apple common in all groups . Therefore divide 6000/60= 100
  
  Make 100 groups of 60 apples each.
  Now, 1,2,5,7,11,13,14,17,19,22,23,25,26,29,31,34,35,37,38,41,43,46,47,49,53,55,57,59 =28
  will be perfect apples in group of 60 apples.
  Therefore for 100 groups =28*100@=2800 perfect apples.

• 6000-2000(3rd apple)> 4000-1500(4th apple)> 2500-600(10th apple)> 1900
  1900+500(LCM no. of 3 & 4)> 2400, 2400+300(lcm no. 4 & 10)>2700, 2700+200(lcm f 3 & 10)> 2900,2900+50(lcm f 3,4,10)>2950ans

• damaged apple:6000/3=2000
  not ripened apple=6000/4=1500
  chemical apple=6000/10=600
  total=(2000+1500+600)=4100
  so,apples ready to eat=6000-4100=1900

• lcm of 3,4,10=60
  so multiple of 3,4,10=(3,6,9,15,18,21,27,30,39,45,42,51,54,57,4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,10,50)=32 not eatable so 28 eatable
  so (6000*28)/60=2800

• in every 10 fruits , 6 are unable to eat i.e) 4 can be eaten
  so the ratio 4:6 in every 10
  no of apples can be eaten is 4/10 *6000 = 2400

• damaged apple = 2000
  Remaining apple = 4000
  every 4th apple is not ripened which means 1000 apples out of 4000 is not ripened.
  So the remaining apples are 3000
  Every 10th apple is made by chemicals. So according to ques 300 apples are made by using chemicals. so the remaining apples ready to eat are 2700.
