- The lowest number is 110
Explanation:
avg of 3 numb is 135
(x + y + z) / 3 = 135
diff. b/w 2 values is 25 so
x = y - 25
z = y + 25
[(y-25) + y + (y+25)]/3 = 135
[y-25+y+y+25] / 3 = 135
3y/3=135
y=135
so x = 110 ; y = 135 ; z = 160
The lowest number is 110

- The answer is 110
Explanation given that x+y+z/3=135
So x+y+z=405
Then by given details
x+25=y
y+25=z
Solve
y-25+y+y+25=405
You will get y=135
So,
135-25=x
x=110
Obviously z+25=greater than x - 6 years agoHelpfull: Yes(2) No(0)
