36 = 2t + u
A. t = 10, u = 16
B. t = 10, u = 4
C. t = 14, u = 20
D. t = 16, u = 22
Answer:
Let the full marks be y.
Then, the statement become : 30 marks is 40 % of y.
to solve for y;
40% of y can be written as
Then,
from the given condition we have;
or
Multiply both sides by in above equation;
Simplify:
Then, the full marks (y) = 75.
Therefore, 30 marks is 40% of 75.
Check:
30 =
30 =
30 =30 [True]
x = log2y
y = logx2
