Question

15. What is the minimum and maximum number of digits in the sum if we add any two 3-
digit numbers?​

Answer 1

Answer:

greatest number made by using 3 digits = 999

sum = 999+999 = 1998

so, maximum number of digits = 4

smallest number made by using 3 digits = 100

sum = 100+100 = 200

so, minimum number of digits = 3

Answer 2

Given :   add any two 3-digit numbers

To Find :  minimum and maximum number of digits in the sum

Solution:

Largest  3-digit numbers numbers = 999

Smallest 3 -digit numbers numbers = 100

100 + 100  = 200 is  the minimum sum  3 Digit number  

Hence minimum digits = 3

999 + 999  = 1998  is the maximum sum  4 Digit number

Maximum digits = 4

Hence minimum and maximum number of digits in the sum will be 3 and 4 respectively
