Answer: 44.5
Step-by-step explanation:
Assume highest marks as h and lowest as L.
h = twice L + 5
h = 2 x L + 5
h = 85 as given
L = 85 divided by 2 - 5
L = 45.5 - 5
L = 44.5

Step-by-step explanation:
Let the lowest mark be x.
The highest marks is 85.
The highest marks is twice the lowest marks plus 5 = 2x + 5 = 85
A.T.Q;
2x + 5 = 85
or, 2x = 85 - 5
or, 2x = 80
or, x = 80/2
Therefore, x = 40
Thus, the lowest marks is 40.
