Maths Puzzle
if 15% of X is added to X and 5% of the result is subtracted from the result, then the value of X
1) increased
2)decreased
2)no change
4)depend on x
Read Solution (Total 3)
-
- 1)increased
Let assume X =100
15% of 100 = 15
Now, new value X = 100+15 = 115
5% of 115(new result) = 5.75
So, 115-5.75 = 109.25
So, X is increased. (100 increased to 109.25)

X+0.15X=1.15X
50% of 1.15X=0.575X
Therefore on subtracting 1.15X-0.575X=0.575X < X - 12 years agoHelpfull: Yes(0) No(0)
