Oranges can be packed in sets of 10 oranges in a box type A or 25 oranges in box type B.A carton comprising of 1000 oranges of type A and type B is packed. How many different combinations possible in the number of type A and type B boxes while organizing the oranges?
a)21 b)20 c)19 d)18
Read Solution (Total 9)
-
- for given data, the expression will be 10x+25y=1000
the above exp will be satisfied only with multiples of 2 up to 38.
so no. of combinations are 19.
if oranges are packed in type A boxes only= 1 way
if oranges are packed in type B boxes only= 1 way
so tatal = 19+1+1=21 - 11 years agoHelpfull: Yes(26) No(8)
- ans is 21
AS for Type B it can be 0 50, 100,150,200,,(similarly(by adding 50)) upto 1000.
There are 21 possible ways for packing the 1000 oranges.

- pairs will be solution of 10a+25b=1000
that could be (5,38),(10,36),(15,34).......(95,2)
so possible nos are 19 if a and b type is there and if it may be possible that only one will be their then possible pairs will be 19+2=21.... - 11 years agoHelpfull: Yes(4) No(3)
- I think its 19 bcoz there are both type A and type B oranges packed in carton
- 11 years agoHelpfull: Yes(4) No(0)
- .A carton comprising of 1000 oranges of type A and type B
this statement says about both type so I think ans should be 19
by removing only A and only B sets.

- 10x+25y=1000
=>2x+5y=200
now,x can take values 0,5,10,15..100
0 being the case of all type b and 100 the case of all type a.
using A.P. 0+5*n=100
=>n=20
so according to me the ans should be 20.. - 11 years agoHelpfull: Yes(2) No(1)
- is it 21 or 19? anyone pls do explain me
- 11 years agoHelpfull: Yes(2) No(0)
- answer is 21
- 11 years agoHelpfull: Yes(1) No(2)
- as per the given question the equation formed is
10a+25b=1000
=> 2a+5b=200, put a=0
we get b=40
only integer values possible so, put a=5 we get b=38 , rest combinations are
(a,b)=(0,40), (5,38),(10,36),(15,34),----------------(100,0) = 21 combinations - 9 years agoHelpfull: Yes(1) No(0)
