5579, 5759 and 5975 are three possible answers.
5858, 5885, 5588
5777, 6479 and 6488.
69000
It is 100,000 rounded to the nearest hundred thousand
As rounded to nearest hundred thousand it becomes 7 909 000. This is because 688 exceeds 500 ie half of 1000. So 8 thousand becomes 9 thousand. So 908 thousand becomes 909 thousand.
5500
46000 is nearer to 50000 than it is to 40000. So, to the nearest ten thousand 246000 becomes 250000.
69000
781579 rounded to the nearest thousand becomes 782,000
It is 100,000 rounded to the nearest hundred thousand
