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

Ans 8:

Ankit Kumar Mistry from Kalyani Public School, Kolkata
Class : Class 5
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.

Subject :IMO    Class : Class 3

Ans 1:

ASHMI Narkar from Vibgyor High Airoli, Navi Mumbai
Class : Class 4
No answer is C admin is right

Ans 2: (Master Answer)

Admin from revisewise, Noida
Class : Class 1

The correct answer is C.

Handshakes by the first child = 6 (with remaining 6 children)

Handshakes by the second child = 5 (as the handshake with the first child is already counted)

Then, handshakes by the third child = 4 (as the handshakes with the first and second child are already counted)

Similarly, handshakes by the fourth, fifth and sixth child are 3, 2 and 1 respectively.

Since, the last child's handshakes are already counted, he/she will not make any new handshakes.

Therefore, a total of (6 +5 +4 + 3 + 2 + 1) = 21 handshakes took place.
