Answer 1

Answer:

write the question properly Dear ...

Answer 2

Therefore '672' that is '379' will be the largest number. ( Option-a )

Given:

The first digit of the number is subtracted by '1' and the third digit is subtracted by '3'.

And then both the digits are interchanged with each other.

To Find:

The largest number among the given options after doing the given operations.

Solution:

The given question can be solved very easily as shown below.

Operations to be performed:

1.) The first digit of the number is subtracted by '1' and the third digit is subtracted by '3'.

2.) And then both the digits are interchanged with each other.

Option-a: 379

First Digit = 3 → subtracting 1 = ( 3 - 1 ) = 2

Second digit = 9 → subtracting 3 =  ( 9 - 3 ) = 6

After interchanging the new number becomes = 672.

Option-b: 536

First Digit = 5 → subtracting 1 = ( 5 - 1 ) = 4

Second digit = 6 → subtracting 3 =  ( 6 - 3 ) = 3

After interchanging the new number becomes = 334.

Option-c: 468

First Digit = 4 → subtracting 1 = ( 4 - 1 ) = 3

Second digit = 8 → subtracting 3 =  ( 8 - 3 ) = 5

After interchanging the new number becomes = 563.

Option-d: 355

First Digit = 3 → subtracting 1 = ( 3 - 1 ) = 2

Second digit = 5 → subtracting 3 =  ( 5 - 3 ) = 2

After interchanging the new number becomes = 252.

Hence 672 > 563 > 334 > 252

Therefore '672' that is '379' will be the largest number.
