Explanation:

1. “x1 is a clone of x” means x1 is identical to x in terms of the physical attributes namely,
 height, weight and complexion. Given, height, weight and complexion only form a
complete set of attributes for an entity, cloning is an equivalence
relation. What is your impression about this statement ?

5. Four your ATM debit card, you have a 4-decimal-digit personal secret
code. In the absence of any clue, a brute-force attack takes time-‘t’ to
crack the code on an ATM terminal. Therefore ‘t’ is the secure-time for a
customer to report in case the card is misplaced. Your Bank has decided to
facilitate an increased secure-time. Out of the following, which option
should provide the largest rise in the value of ‘t’ ?

(A) Instead of 4-decimal-digits, maintain the personal secret code in 4-hexadecimal-digits.
(B) Instead of 4-decimal digits, maintain a 5-decimal-digit personal secret code.
(C) Reduce the processing speed of the ATM terminals to the half of their current speed.
