What is the smallest number of five digits formed by using the digits 2, 4, 0, 3, 5?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 20345
The smallest number puts the smallest digits in the highest places, but a five-digit number cannot begin with 0.
First place: the smallest non-zero digit, 2
Remaining places: the other digits in increasing order, 0, 3, 4, 5
Number: 20345
02345 in Option (1) is really the four-digit number 2345.
