Answer 2

5. PLACE VALUE OF 1st 9= 9000000

PLACE VALUE OF 2nd 9= 900

DIFFERENCE BETWEEN BOTH THE NINE IN THE NUMBER 79520986= 9000000-900

= 899910

6. PLACE VALUE OF 7= 7000000

FACE VALUE OF 7= 7

DIFFERENCE BETWEEN PLACE VALUE AND FACE VALUE OF 7 IN 27650935= 7000000-7

= 6999993

7. THERE ARE 9,00,000 6-DIGIT NUMBERS IN ALL.

12. THE NUMBER THAT COMES AFTER 9547999= 9548000

13. THE NUMBER THAT COMES BEFORE 9900000= 9899999

14. THE NUMBER THAT COME BEFORE 10000000= 9999999

15. 3-DIGIT NUMBERS USING 2,3,4 = 234,324,423,432 342,243

16. THE SMALLEST NUMBER OF DIFFERENT DIGITS USING 3, 1, 0, 5 AND 7= 10357, 30157, 50137, 70135

17. THE LARGEST NUMBER OF DIFFERENT DIGITS USING 2, 4, 0, 3, 6 AND 9.

18. 735821= 735,821
