Question

Form the greatest and the smallest 4-digit numbers using the given digits, without repetition:​ 1, 8, 5 and 3

Answer 1

Finding the smallest and largest 4- digit number using the given digits ​

Given digits = 1, 8, 5 and 3​

Since 8 > 5 > 3 > 1​

Thus, the greatest 4-digit number = 8531​
And the smallest 4-digit number = 1358​

Hence, 8531 is the greatest 4-digit number & 1358 is the smallest 4-digit number.​
