The correct answer is 'B'. As you have been asked - 84 thousands 60 hundreds 50 tens = 90,150 16 thousands 82 hundreds 28 tens 19 ones = 24,499 Now over here we have not been given an equation symbol. So, we assume that 90,150 - 24,999 = 65,651 Therefore the answer is 'B: 65,651'

There was a minus sign in between which was missing. It has been corrected.
First Number = 84000+6000+150 = 90150
Second Number = 16000+ 8200 + 280 + 19 = 24499
Difference = 90150 - 24499 = 65651
