Answer 1

Step-by-step explanation:

option is

B

5300

⇒ The given two numbers are 5679 and 422.

⇒ In number 5679, its tens digit is 7, which is greater than 5.

⇒ So, we increase the digits at hundreds place by 1 and replace each one of the digits at tens and ones place by 0 to round off the given number to its greatest place.

∴ Round off 5679 to its greatest place is 5700

⇒ In number 422, its Itens digit is 2, which is less than 5.

⇒ So, we replace each of the tens and ones digits by 0 and keep the other digits as they are to round off the given number to its greatest.

∴ Round off 422 to its greatest place is 400

∴ Required number = 5700−400=5300
