The correct answer is D. Because:27.45 = .45 =5 ones and 4 tens. 27. = 7 ones and 2 tens. Bring .45 and 27. together to get 27.45. And according to the calculation the answer is 2 tens. So it will be D= 20 as 2 tens is written as 20 in expanded form.

yet another wrong answer by IMO.. Keep it up..

## Ans 2:

Class : Class 2
The ball can 'roll'. Can it be considered as sliding? Moreover, if a cube/cuboid is placed in a slanting surface, it can slide

## Ans 3:

Class : Class 3
Ball cant slide however cube can slide as it has flat surface

## Ans 4:

Class : Class 2
Ball can roll but it is saying that ball can slide.So correct answer is cube

## Ans 5:

Class : Class 3
Ball can roll..it canÃ¢Â€Â™t slide...very bad...wrong answer by IMO...

## Ans 6:

Class : Class 3
Yes, ball rolls as it's sphere shape. Flat surface objects slide. So, this is wrong answer given by the team.

## Ans 7:

Class : Class 1
The Ball can roll. As cube has flat surface it can slide. so correct answer should be cube

0

Class : Class 6
A) 0.

Class : Class 1
It is A i.e 0

Class : Class 7
0 is the answer

Class : Class 6

## Ans 6:

Class : Class 5
not possible question

## Ans 7:

Class : Class 6
From the given table, we have A = 18,732 10,923 = 29,655 B = 18,732 8,473 = 27,205 C = 10,923 9,018 = 19,941 and D = 9,018 8,473 = 17,491 Now, A - B = 29,655 - 27,205 = 2,450 C - D = 19,941 - 17,491 = 2,450 Ã¢ÂˆÂ´ (A - B) - (C - D) = 2,450 - 2,450 = 0.

## Ans 8:

Class : Class 6
Yes,0 is the answer

Class : Class 6
a 0

## Ans 10:

Class : Class 7
See,deepak if 2-2 =0 ,then if the minued and the subtrahend are equal, the diff-erence is 0.

## Ans 11:

Class : Class 6
2450 - 2450 = 0 so the answer is .......................... A

## Ans 12:

Class : Class 7
The answer is A:0if you write the number sentence (given:(A-B)-(C-D)),each number will add and subtract itself(without the bracket):10923 18732 - 8473 - 18732 - 10923 - 9018 8473 9018from this we can say that the answer is 0.
