(a) 56
(b) 40
(c) 33
(d) 57

Difficulty Level: Medium

Ans. Option (c) is correct.
Explanation:
Given passing marks = lowest marks – 12 = 45 – 12 = 33

Q. 3. If one student Aavya of another class who scored 9 marks more than the doubled of lowest marks of this class, find the aavya’s marks:
(a) 92
(b) 50
(c) 89
(d) 99

Difficulty Level: Medium

Ans. Option (d) is correct.
Explanation: Aavya score = 2 × Lowest marks + 9
= 2(45) + 9
= 90 + 9
= 99

Q. 4. Find the highest marks.

Difficulty Level: Hard

Ans. 80

Explanation: let the highest marks be $x$ according to the question, lowest marks

$$
\begin{aligned}
& =\frac{1}{2} \text { (highest marks) }+5 \\
45 & =\frac{1}{2}(x)+5 \\
45-5 & =\frac{1}{2} x \text { [transposing } 5 \text { to LHS] } \\
40 & =\frac{1}{2} x \\
40 \times 2 & =x \text { [multiplying both sides by } 2] \\
80 & =x \\
x & =80
\end{aligned}
$$
