Answer:
75
Step-by-step explanation:
Let full marks be x
Then pass marks is 40% of x which is 0.4x
As per given, we have
22= 0.4x - 8
Solving for x
0.4x = 30
x = 30/0.4
x = 75
So full marks is 75
Answer: The correct option is,
C. x + 12 ≤ 2(x − 3)
Step-by-step explanation:
Given inequalities,
x + 12 ≤ 5 − y and 5 − y ≤ 2(x − 3)
Let a = x + 12, b = 5 - y and c = 2(x-3)
Here, a ≤ b and b ≤ c
Since, by using the transitive property of inequality,
⇒ a ≤ c
⇒ x + 12 ≤ 2(x − 3)
Therefore, OPTION C is correct.
