Question

Verify with numbers 387 and 982 that the difference between a 3 digit number and it's reverse is always 99 times the difference between the hundreds and the ones digit​

Answer 1

Answer:

For number 387

Reverse of 387 is 783

Difference = 783 - 387 = 396

Difference between the hundreds digit = 7 - 3 =4

Difference between the ones digit = 7 - 3 = 4

99 times 4 = 99 × 4 = 396

For number 982

Reverse of 982 is 289

Difference = 982 - 289 = 693

Difference between the hundreds digit = 9 - 2 = 7

Difference between the ones digit = 9 - 2 = 7

99 times 7 = 99 × 7 = 693

Thus it is verified.
