class 8 chapter 1 of maths mcq test in chapter test section Q.2 answer is wrong. it should be a) instead of c).

The provided answer is correct.

The additive inverse of a number "a" is "–a", because when on adding a with –a, we get 0, which is the additive identity.

So, the additive inverse of 0 is –0, which is same as 0.

Thus, the additive inverse of 0 is 0.

However, the the multiplicative inverse of 0 does not exists as division by 0 is not defined.

 

Hope now it will be cleared to you.

Dear Sumir,

       You are saying that additive inverse of 0 doesn't exist. No, The additive inverse of 0 is 0. Because 0+0=0

       But how can multiplicative inverse of any number can exist ? The answer should be c) only.

Hope you understood.
