A student was asked to divide a number by 12. Instead he divided the number by 24. In doing so he got a quotient which was 16 less than the original number. Which of the following cannot be the value of that number. A) 394 B) 398 C) 396

Answer 1

If x is the original number,
x/24 = x-16
Comes out a fraction.

If, on the other hand, you meant to say

he got a quotient which was 16 less than the correct quotient, then we have

x/24 = x/12 - 16
x = 384

I suspect you have garbled the question.
