Find the number WXYZ divisible by 36?
i)let the digits be5,4,3,6 -not in that order
ii)sum of last two digits is 9
iii) sum of middle two digits is 7
if one is sufficient then ans as A || if two is sufficient then ans as B || if all are necessary then ans as C || if nothing is needed then ans as D

• c) All are necessary
  
  a) If number is divisible by 36, then last two digits can be 6 or 4 from the given digits.
  b) Given, sum of last two digits is 9, so possible numbers: _ _ 54 or _ _ 36
  c) As the sum of middle two digit is 7, so only possible combination is 5436.
  Hence all the statements (i), (ii) & (iii) are necessary to answer.
