by 7
 Question Submitted By :: General-Aptitude
I also faced this Question!!     Answer Posted By  
# 1
Sol: the remainder of a^c + b^d when it is divided by x is
same as the sums of rems of a,b to the power c and d.
2222/7 has a remainder of 3 and 5555/7 has a remainder of 4.
So (3)^5555 mod 7 + (4)^2222 mod 7 is the same as
(3)^5 mod 7 + (4)^2 mod 7 = (5 + 2)mod 7 = 0
Is This Answer Correct ?    12 Yes 2 No
# 2
