(A) 780000

(B) 789000

(C) 790000

(D) 800000

CONCEPT TO BE IMPLEMENTED

Rule for rounding off a number :

Discard all digits to the right of the nth place , if the discarded number is less than half a unit in the nth place , leave the nth digit unchanged ; if the discarded number is greater than half a unit in the nth place , add 1 to the nth digit .

If the discarded digit is exactly half an unit in nth digit leaving the nth digit unaltered if it is an even number but increase it by 1 if it is an odd number

EVALUATION

Here the given number is 788948

Digit at thousands place = 8

Digit at hundreds place = 9

9 > 5

Now the digit in the hundreds place is greater than 5

So hundreds place is replaced by 0 and the thousands place is increased by 1

Thus rounding off 788948 to the nearest one thousand we get 789000

FINAL ANSWER

Hence the correct option is (B) 789000
