1.	The product of successor and predecessor of 999 is(A) 999000 (B) 998000 (C) 989000 (D) 1998
Answer» (B) 998000 The number which comes immediately before a particular number is called its predecessor. The successor of a whole number is the number obtained by adding 1 to it. So, Successor of 999 = 999 + 1 = 1000 Predecessor = 999 – 1 = 998 Then, product of successor and predecessor of 999 is = 1000 × 998 = 998000

The product of successor and predecessor of 999 is(A) 999000 (B) 998000 (C) 989000 (D) 1998

Answer»

(B) 998000

The number which comes immediately before a particular number is called its predecessor.

The successor of a whole number is the number obtained by adding 1 to it.

So, Successor of 999 = 999 + 1 = 1000

Predecessor = 999 – 1 = 998

Then, product of successor and predecessor of 999 is = 1000 × 998

= 998000
