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

Munirasu  (9 years ago)

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

Anshika Saxena  (9 years ago)

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.
