12. The statement ' x+3 = 9' is true sometimes.
How is this explained?
Let x= 6,
6 + 3 = 9 (true)
Let x= 5 ,
5 + 3 = 8 (not true)
13.<u> Option c</u>. The statement 'multiplicative inverse of a number is less than the original number' is true for all numbers greater than 1.
How is this explained?
Let us consider some numbers,
a) 1
The multiplicative inverse of 1 = 1
Thus, multiplicative inverse of this number is not less than the original number.
b) 2 (greater than 1)
The multiplicative inverse of 2 = 1/2
multiplicative inverse of this number is less than the original number.
c) 8/7 (greater than 1)
The multiplicative inverse of 8/7 = 7/8
Here, multiplicative inverse of this number is less than the original number.
