6000 apples are collected in which every third apple is small apple,every fourth is green apple and every tenth apple is spoiled. what is the number of perfect apples?
Read Solution (Total 20)
-
- Spoiled apple=600
Green apple=1500
Small apple=2000
Common no that are small green as well as spoiled=
100=
Ans=2000 - 9 years agoHelpfull: Yes(5) No(10)
- spoiled apples=600
green apples=1500
small apples=2000
green apples and small apples are perfect
so 6000-600=5400 - 9 years agoHelpfull: Yes(4) No(1)
- total number of apples 6000
so every third apple is small... so number of small apples =6000/3 =2000
but in this we have also calculated some apples which are green(every forth apple) and spoiled(every 10th apple). so we have to subtract them. for eg every 12th apple will be small and green (3*4=12). so
number of multiples of 12 in 6000= 6000/12=500
similarly number of multiples of 30 (every 30th apple will be both small and spoiled)= 6000/30=200
number of small apples only=2000-500-200=1300
similarly no of green apples =6000/4=1500
eliminating the no of small apple which are counted in this =(6000/12)=500
eliminating the no of spoiled apple=6000/40=150
no of spoiled apple=6000/10=600
eliminating no of small apple=6000/30=200
eliminating no of green apples=6000/40=150
number of correct apples= 6000-(2000-500-200)-(1500-500-150)-(1500-500-150)=3500
and by the way do have an apple for the day!!!!! - 9 years agoHelpfull: Yes(4) No(0)
- There are total number of apples = 6000
Spoiled apples = 600
Small apples = 2000
Green apples = 1500
Total = 4100
In that 500 apples are Green and small both, 150 apples are small and spoiled, 200 apples are spoiled and green and 50 apples are spoiled,small and green
So, total number of perfect apples = 4100 - (500+150+200+50) = 3200 apples
Answer = 3200 - 9 years agoHelpfull: Yes(2) No(0)
- So the third was bruised, the fourth was too green, and the tenth was bruised. So if you get a least common factor it would be every 60 apples because 3, 4, and 10 all fit into 60. This means that 60 is dividable by all of these numbers 3, 4, or 10.
Every third of 60 is 60/3 = 20 apples, every 4th is 60/4 = 15 apples, but remember that some apples are both too small and too green. That means that every 1 out of 12 are both small and too green, so get 1/12 of 60 and subtract that number from the 15. The reason you use 12 is because 3 and 4 both fit into 12 as in if you multiply them.
So every third apple is 20 + every fourth is 15 minus 5 apples, because you don't count the same apple again equals 30 apples. So 30 apples includes the too small and too green apples. But we're still not done yet.
Now count the every 10th apple, but again don't count the same apples. 1/10 of 60 is 6 apples, but if you find the least common factor of 3 and 10 or 4 and 10 you get 20, 30, 40, and 60. So don't count 4 apples. That means for every apple that is bruised and only bruised is another 2 apples.
Now add 2 to that 30 apples to get 32 apples. So 32/60 every 60 apples are bad. Or you can multiple these numbers by 100 to get 3200 out of every 6000 apples are bad. Leaving 2800 good apples. - 9 years agoHelpfull: Yes(1) No(0)
- what is the answer
- 9 years agoHelpfull: Yes(0) No(0)
- 7 out of 10 apples are perfect
so out of 6000 -> 4200 are perfect apples - 9 years agoHelpfull: Yes(0) No(3)
- How but neeraj canu explain me
- 9 years agoHelpfull: Yes(0) No(0)
- i think
2000 apples are smll
1500 apples are grn
600 apples are spoiled
so guess out what will be the answer - 9 years agoHelpfull: Yes(0) No(1)
- perfect apples = (7/10)*6000 = 4200
so ans is 4200 - 9 years agoHelpfull: Yes(0) No(5)
- 6 Out of 10 are imperfect apples so out of 6000 total imperfect apples are [(6*6000)/10] 3600
- 9 years agoHelpfull: Yes(0) No(2)
- ans 4500
1/3*1/4*1/10=3/4
6000*3/4
4500 - 9 years agoHelpfull: Yes(0) No(1)
- perfect apple=6000-2000-1500-600+6000/lcm of 3,4,10=1000
- 9 years agoHelpfull: Yes(0) No(0)
- **SG*****10
if among each 10 there are 3 apples defected .
so among 6000 defected will be.. 6000*3/10=1800
so perfect ones are 6000-1800=4200 - 9 years agoHelpfull: Yes(0) No(1)
- confuse . plz explain this question in deatail

- every 3rd 4th and 10 th
hence in 10 apples 6 are good hence in 6000 , 3600 are in good condition - 9 years agoHelpfull: Yes(0) No(1)
- Every 3rd apple is small= n(3).
Every 4th apple is green= n(4).
Every 10th apple is spoiled= n(10).
Imperfect apples= n(3 U 4 U 10)= n(3) + n(4) + n(10) - n(12) -n(20) -n(30)+ n(60)
= (6000/3) + (6000/4) + (6000/10) - (6000/12) - (6000/20) - (6000/30) + (6000/60)
= 2000 + 1500 + 600 -500-300-200 +100
= 3200
Then the no. of perfect apple= 6000 -3200
=2800 - 9 years agoHelpfull: Yes(0) No(0)
- 6000/3=2000
- 9 years agoHelpfull: Yes(0) No(0)
- 2650
