120 - 144 -->25 numbersBox 1-25, 26-50, 51-75, 76-100, 101-125, 126, 127 and 128So total of 6 boxes, isn't it?? ( With same numbers )
Ahaan! I interpreted the question in a different way.

Raju has to put atleast 120 Oranges in one box and maximum he has 144 Oranges which can be put all together too.

So, taking 120 Oranges in Box 1, we are left with 144 - 120 = 24 Oranges. Now he can put one orange each in next 24 boxes leaving behind 128 - 1 - 24 = 103 Boxes having no oranges which is the least number of boxes having same number of Oranges.

This is how I solved this question! :splat:

yaar yeh toh Q hi samajh nahi aaya. oranges ka koi figure toh de nahi rakha. explain karo Q.
CAT 2001 question hi ye..
@ScareCrow28 said:
Maximum 128 he ni hogaya
achha hann , sry
@ScareCrow28 said:
Isme bhi to 120-144 he dalenge..to hogaye na 6??
nahi...lekin minimum 5 hi rahega....

minimum lena padega na..?

Maximum will be when you put 120 Oranges in one box and rest 24 in one box. So, left boxes having same number of Oranges (Zero) = 128 - 2 = 126.
maximum will be when he puts 120/121/122.. in all the 128 boxes..there is no number limit on oranges


A three-digit number abc is divisible by €žX €Ÿ when 2a + 3b + c is divisible by 7. What is X?
1. 7 2. 3 3. 5 4. 9

But each box can hold 120 to 144 oranges,but the by your method,the tota# of l oranges itself
144,right?;)

100a + 10b + c mod 7 = 2a + 3b + c mod 7

which means x should also be 7;)

Yeah I took total oranges as 144 as it said ''144 at the most''. Either that was for upper limit of the capacity of box or else the number of oranges. If capacity taken, then the number of oranges won't have any fixed limit. So, I took it the other way. Might be wrong. Dunno! :|

2a+3b+c= 7k
100a+150b+50c=350 k
100a+10b+c+(140b+49c)
100a+10b+c should be divisible by 7....

I interpreted 144 as the max. number of Oranges. :roll::roll:

Dekho 5 boxes to hogaye..ab bache 3 boxes..usme bhi to koi number bharna hai na... to atleast 6 hogaye na...
The number of divisors of an odd number is 34. If it is multiplied by 12, the number of divisors will be
1. 278 2. 76 3. 204 4. 216

put various values like 112 / 133 / 511 etc......

everything will be divided by 7
