The correcr answer is B CM = 1000 – 100.

Class : Class 6
A

## Ans 7:

Class : Class 4
If there is C before M that means that we are subtracting 100 from 1000 . We write it as 1000 - 100. Answer : B

Class : Class 4
b is the answer

## Ans 9:

Class : Class 7
The answer is B because CM=C-M=C(100)-M(1000)We cannot subtract 100-1000 So the formula should be 1000-100 l Therefore, TH H T O 1 0 0 0 - 1 0 0 ----------------------- 9 0 0 So, B is the right answer.

Class : Class 2
CM=1000-100

## Ans 11:

The correct option feeded into the question is wrong. It should be C, but the correct answer in this is B!

## Ans 12:

The correct answer would be option C because CM = 900. C=100, M=1000. So, the smaller no. is in the beginning, it will be minus. So, 1000-100 is the correct ans.

## Ans 13:

Class : Class 6
c=100,M=1000 so cm =100-1000 (answer. c)

## Ans 14:

Class : Class 5
The correct answer is b
