Answer 1

Given : Using digit 4,9,0,2  without repetition smallest digit number is 0249

To Find :   true or false.​

Solution:

Using digit 4,9,0,2  without repetition

Hence we need to use all the digit

Leading digit can not be zero as its not a significant digit

and will not be counted

as 00249  and 0249 are same things hence 0 can not be used at thousand place in this case

so smallest 4 digit number can be 2049

Using digit 4,9,0,2  without repetition smallest digit number is 0249 - FALSE
