Answer 2

Given:

Mili’s teacher writes the number 94802 on the board.

To find:

To change just ONE digit in the number so that there is maximum possible increase in the value of the number. The number should remain a 5-digit number.

Solution:

a) If we Change 0 to 9, we get 94892.

   The difference in value is 94892 - 94802 = 90

b) If we Change 4 to 9, we get 99802.

   The difference in value is 99802 - 94802 = 5000

c) If we Change 4 to 5, we get 95802.

   The difference in value is 95802 - 94802 = 1000

d) If we Change 8 to 9, we get 94902.

   The difference in value is 94902 - 94802 = 100

Hence, when we Change 4 to 9 (Option b), there is maximum possible increase in the value of the number.
