| (i) | (ii) | (iii) | (iv) | |
| A | x = b/a | commutativity | positive | 1 |
| B | x = –b/a | commutativity | negative | 2 |
| C | x = b/a | transposition | negative | 2 |
| D | x = –b/a | transposition | positive | 1 |

(D): (i) We have, ax + b = 0
⇒ ax = – b
(ii) The shifting of a number from one side of an equation to other is called transposition.
(iii) We have, ax = b
⇒ 
which is the required solution
Given that a and b are positive integers.
∴ Solution of the equation ax = b has to be always positive.
(iv) Linear equation is of the form ax + b = 0 i.e., only one variable with power 1.

Both A and B is correct as it depends that that how the Dice is tilted with 5 dots on upper side
Ans 5:
Class : Class 6
It should be 5 dots, as we know that the dots on opposite sides add up to 7. But, even if we go according to the figures given, it is clearly 1 dot.
Ans 6:
Class : Class 6
The opposite sides of the dice when added are 7 so if 2 dots are at the bottom 5 dots should be on the top.
Ans 7:
Class : Class 8
it will be athe 5 dots is on the side and the 3 side toothe 1 side will face up if the 2 side is facing at bottom

THE CORRECT ANSWER IS ANSWER OPTION C BECAUSE MMMMDCCCI=4701 AND MMMMDCCCI=4801. So ,4701+4801=9502. Some people say that a roman numeral cant be repeated more than 3 times but in fact ( in rare cases )they can be used more than 3 times. like 4000 IS WRITTEN AS MMMM.
