Maths Puzzle
Let [x] denote the greatest integer less than or equal to x. Let x and y satisfy the simultaneous equations
y = 2[x] + 2
y = 3[x - 2] + 2.
If x is not an integer, then x + y is
Read Solution (Total 3)
-
- Y-2[X]=1
Y-3[X]= -4
SOLVING WE GET [X]=5
AND Y =11
ADDING [X]+Y=16 - 8 years agoHelpfull: Yes(1) No(0)
- y = 2[x] + 2
y = 3[x - 2] + 2
2[x]+2=3[x - 2] + 2
2[x]+2=3[x]-6+2
[x]=6
so y=14
so x+y lies in[20,21) - 11 years agoHelpfull: Yes(0) No(3)
