If n is a whole number such that n + n = n, then n =?
1 1
2 2
3 3
4 None of these.
Explanation:
None of these. Solution: Here, 0 + 0 = 0, 1 + 1 = 2, 2 + 2 = 4 ….. So, the statement n + n = n is true only when n = 0. Hence, the correct option is (d).

The product of the successor and predecessor of 99 is:
1 9800
2 9900
3 1099
4 9700
