The answer is 25 but I do not know the rule. If someone else knows the rule feel free to edit my answer. first thing i would like to tell that their no particular rule to solve this problem. But if we consider the working of calculator then the addition will be done as follows. ((((((((1+2)+3)+4)+5)+4)+3)+2)+1) = 25 (((((((3+3)+4)+5)+4)+3)+2)+1) = 25 ((((((6+4)+5)+4)+3)+2)+1) = 25 (((((10+5)+4)+3)+2)+1) = 25 ((((15+4)+3)+2)+1) = 25 (((19+3)+2)+1) = 25 ((22+2)+1) = 25 (24+1) = 25 solve from innermost bracket towards outer This is just a consideration of calculator if you solve through calculator the producer will look as above. If any one knows any simple answer please feel free to continue this discussion.
