Let's analyze the multiple-choice statements given in the question one by one for Question 74 and Question 75:
74. Which of the following is not true?
A) ( − 25 ) /5 = − 5

This is true because when you divide − 25 by 5 , you get − 5 .

B) 4/1 = 4

This is true because dividing 4 by 1 gives 4 .

C) 12/0 = 12

This is false because division by zero is undefined in mathematics. You cannot divide any number by zero.

D) 0/2 = 0

This is true because dividing 0 by any non-zero number results in 0 .

The incorrect statement here is C) 12/0 = 12 .
75. The place value of 5 in the numeral 18,56,22,387
