Which of the following is not representing a nibble? Correct Answer x<= STD_LOGIC_VECTOR (0 TO 4)

A nibble is a group of 4 bits. In case of option x<= “0101”, it is clear that x is a group of 4 bits. Similarly in x<= STD_LOGIC_VECTOR(3 DOWNTO 0) and x<= BIT_VECTOR (1 TO 4), we have four bits. But, in option x<= STD_LOGIC_VECTOR (0 TO 4), we have 5 bits from 0 to 4. Therefore, option x<= STD_LOGIC_VECTOR (0 TO 4) is not a nibble.

Two boys are playing on a ground. Both the boys are less than 10 years old. Age of the younger boy is equal to the cube root of the product of the age of the two boys. If we place the digit representing the age of the younger boy to the left of the digit representing the age of the elder boy, we get the age of the father of the younger boy. Similarly, we place the digit representing the age of the elder boy to the left of the digit representing the age of the younger boy and divide the figure by 2, we get the age of the mother of the younger boy. The mother of the younger boy is younger than his father by 3 years. Then, what are the ages of elder and younger boys ?
