Following conditions apply:
(i) If the number is a prime number the first digit is to be replaced by “@” and the last digit is to be replaced by “&”
(ii) If the number is a perfect square it is to be divided by two and the quotient is to be coded as per these conditions and the letter/ symbol code that would apply
(iii) If the first digit as well as the last digit is odd, both are to be coded as #
(iv) In case both (i) and (iii) are applicable condition number (i) will apply
1. Find out the combination for: 319602
a. #D&Q%#
b. @D&Q%&
c. @#&F%R
d. None of these
2. Find out the combination for 627
a. #RB
b. #R#
c. #BR
d. FRB
3. Find out the combination for 1936
a. #&@R
b. #FQ
c. &FQ
d. #&@F
4. Find out the combination for 773
a. #B#
b. BB@
c. @B&
d. #B@
5. Find out the combination for 1000
a. D%%
b. #%%%
c. @%%&
d. None of these
1. Option c
None of the four conditions apply on the number so the digits will be coded to their letter/symbol equivalent. So 3 will become @, 1 = #, 9 = & and so on.
2. Option d
None of the four conditions apply on the number so the digits will be coded to their letter/symbol equivalent. So 6 will become F, 2 = R and 7 = B.
3. Option c
Since 1936 is a perfect square of 44 condition number (ii) will apply and the number to be coded will now be 1936/2 = 968. The correct combination is &FQ.
4. Option c
Since 773 is a prime number condition number (i) will apply.
5. Option b
None of the four conditions apply on the number so the digits will be coded to their letter/symbol equivalent. So 1 will become #, 0 = % and so on.
