4. If x^y denotes x raised to the power y, Find last two digits of (1141^3843) + (1961^4181)
a) 02
b) 82
c) 42
d) 22

• (1141^3840) x (1141^3) + (1961^4180) x (1961^1) = [1x(41^3)] + [1x61]
  ---------------------------------------------
  Calculate only for last 2 digits
  41^3 = 41x3 = 21
  61^1 = 61x1 = 61
  --------------------------------------------
  = 21+61 = 82
  
  So option B is the correct answer.
