0

1

51

41

Hari writes the number sentence 90 + 41 = * + 90. To find the number that goes into the box, we need to find the missing number that, when added to 90, equals 90 + 41. Therefore, the missing number is 41.

10) 3-Which of the following is in ascending order?

5234,5243,5324,5342

5234,5324,5342.5343

5342,5324,52435234

5324,5342,5234,5243

The given sequence of numbers is 5234, 5243, 5324, 5342. To determine if it is in ascending order, we compare each pair of adjacent numbers.
