Question

Interchange the digits 7 and 5 in the number 75,683 and find the difference between the new number and the original number.

Answer 1

Given :

• Number = 75,683
• Interchange the digits 7 and 5.

To find :

• the difference between the new number and the original number.

Solution :

⇒ Let's first, interchange them.

• Old number = 75,683
• New number = 57,683

→ Interchange is to exchange the position of one number with the other. And while interchanging, we have to only change the number which we are asked to.

⇒ Now, let's find the difference.

→ Here, the difference is "subtracting".

Difference = Old number - New Number

= 75683 - 57683

= 18000

• Therefore, the difference between the new number and the original number is 18000.
