  1. Identity for the addition of natural numbers
  2. Additive inverse of x
  3. Multiplicative inverse of x
  4. Reciprocal of x

The correct answer is: Identity for the addition of natural numbers


    If x + 0 = 0 + x = x, which is a natural number, then 0 is called identity for the addition of natural numbers. 
    Hence, option(a) is the correct option.

    Which is more, 8000 grams or 8 kilograms? 

    In this question we can also convert 8 kilograms to grams.
    8 kilograms = 8 x 1000 grams
    = 8000 grams
    Now, we have to compare 8000 grams and 8000 grams. Both are the same. So, again we get that neither of them are more than the other one.
    Hence, option(d) is the correct option.

    Rashid and his 5 friends want to drink tea. They use 2 spoons of tea powder for each cup. How many spoons of tea powder is required? 

    Another approach to the question could be that we can add 2 (i.e., the number of spoons of tea powder for each cup) 6 times, which is the number of people who wanted to drink tea.
    Hence, number of tea spoons f tea powder required = 2+2+2+2+2+2 = 12
    Thus, option(d) is the correct option.
