Question

This question is based on the five, three-digit numbers given below.

(Left) 169 837 576 268 715 (Right)

(Example- 697 – First digit = 6, second digit = 9 and third digit = 7) (NOTE: All operations to be done from left to right.)

If all the numbers are arranged in ascending order, the position(s) of how many numbers will remain unchanged?

• A. 2
• B. 3
• C. 1

1. Identify the Original Sequence

The original arrangement of the five numbers from left to right is:

1. 169

2. 837

3. 576

4. 268

5. 715

2. Arrange the Numbers in Ascending Order

Ascending order means arranging the numbers from the smallest value to the highest value:

• Smallest: 169

• Second: 268

• Third: 576

• Fourth: 715

• Highest: 837

The new sequence is: 169, 268, 576, 715, 837.

3. Compare Positions

Let's match the original list against the newly arranged ascending list:

Position	Original Number	Ascending Order Number	Status
1st	169	169	Unchanged
2nd	837	268	Changed
3rd	576	576	Unchanged
4th	268	715	Changed
5th	715	837	Changed

Looking closely at the table, there are actually two numbers whose positions remain exactly the same:

• 169 stays in the 1st position.

• 576 stays in the 3rd position.

Therefore, the final answer is 2.
