Answers
Answer:
Step-by-step explanation:
Greatest = 9874021
Smallest = 0147892
Answer:
The greatest required number is found to be: 9874201 and
The smallest required number is found to be: 1047892.
Step-by-step explanation:
In order to find the greatest number that can be formed by a given set of numbers from 0-9, we can arrange the given numbers in a descending order. Now, we are given to fix a number at a particular place, then we can arrange the numbers in descending order with making an exception of that place.
Now, from the given numbers: 7, 8, 9, 2, 0, 1, 4, we have to fix 1 at the ones place. Arranging in descending order, we get: 9874201 as the greatest number which can be formed.
Similarly, the smallest number that can be found will be found by arranging the numbers in an ascending order.
Repeating the same process as earlier but this time, arranging the numbers in ascending order, we get: 1047892.
