Question

How can you rearrange two digits in the number 2,957,648 so that the value of the digit 4 is 10 times greater?

Answer 1

2,957,468

Explanation:

Each digit to the left is worth 10 times more than the same digit one place to the right.

If 2,957,648 becomes 2,957,468, the 4 moves from the tens place to the hundreds place, and now its value is 400 instead of 40, so it's 10 times greater.
