Class: 7

Subject: Maths

Time: 2 Hr 30 Min.    Maximum Marks: 50

Note:

1. All questions are compulsory.
2. Marks are indicated against each question, attempt every part carefully.

Q.1 Select the correct option (2 × 8 = 8 Marks)

1. 2% of Rs. 50 will be:

   • (A) Rs. 1
   • (B) Rs. 60
   • (C) Rs. 50
   • (D) Rs. 1

   Explanation: 2% of Rs. 50 = (2/100) × 50 = Rs. 1.

2. Each angle of an equilateral triangle is:

   • (A) 60°
   • (B) 90°
   • (C) 120°
   • (D) 80°

   Explanation: In an equilateral triangle, all angles are equal and sum to 180°, so each angle = 180°/3 = 60°.

3. The complementary angle of 50° is:

   • (A) 30°
   • (B) 120°
   • (C) 40°
   • (D) 90°

   Explanation: Complementary angles sum to 90°. So, 90° - 50° = 40°.

4. The sum of two supplementary angles is:

   • (A) 60°
   • (B) 90°
   • (C) 120°
   • (D) 180°

   Explanation: Supplementary angles always add up to 180°.

5. If x + 5 = 7, then the value of x will be:

   • (A) 2
   • (B) 3
   • (C) 12
   • (D) 4

   Explanation: x + 5 = 7 ⇒ x = 7 - 5 = 2. So correct option is (A).

6. The measure of a right angle is:

   • (A) 90°
   • (B) 60°
   • (C) 45°
   • (D) 180°

   Explanation: A right angle measures exactly 90°.

7. The solution of (-28) - (-28) will be:

   • (A) -56
   • (B) 56
   • (C) -18
   • (D) 0

   Explanation: (-28) - (-28) = -28 + 28 = 0.

8. 2/3 + 1/3 is equal to:

   • (A) 1/3
   • (B) 2/3
   • (C) 1
   • (D) 3/3

   Explanation: 2/3 + 1/3 = (2+1)/3 = 3/3 = 1.

Q.2 Fill in the blanks (1 × 8 = 8 Marks)

1. a × 0 = 0 × a = 0

2. 9 × (3) × (-1) = -27

3. Write the formula for the area of a circle: πr²

4. If x/5 = 0, then x = 0

5. The side opposite to the right angle is called hypotenuse.

6. 12.5% = 1/8 (in fraction form)

7. Profit = Selling Price – Purchase Price.

8. Simple interest = (P × R × T) / 100

Question 4

Multiply and express as a mixed fraction. (2 Marks)

(Note: The original text appears to have a formatting issue. Assuming the intended question is: 5 × 6² or similar. Based on available text, the problem is unclear. Please refer to the original question paper.)

(i) 4 × 6⁵

Question 5

A car travels 76 km on 1 liter of petrol. What is the total distance the car will travel on 2 liters of petrol? (2 Marks)

Question 6

Find the area of a triangle whose base is 0 cm and height is 2 cm. (2 Marks)

Question 7

Solve the following equations. (5 Marks)

(Note: The original text has unclear symbols. Assuming standard equations.)

1. 10P + 0 = 00 → Answer: P = 0
2. 2q - 6 = 0 → Answer: q = 3
3. 2q + 6 = 2 → Answer: q = -2
4. 35 = 0 → Answer: No solution (equation is false)
5. 2q = 6 → Answer: q = 3

Question 8

Find the unknown angle in the adjoining figure (where P || Q). (2 Marks)

(Figure not provided. Please refer to the original question paper for the diagram.)

Question 9

Find the supplement of each of the following angles. (2 Marks)

(Note: The original text has unclear angle values. Assuming standard angles.)

1. Angle = 45° → Supplement = 180° - 45° = 135°
2. Angle = 60° → Supplement = 180° - 60° = 120°

Question 10

Find the values of the unknown X and Y in the following figures. (2 Marks)

(Figures not provided. Please refer to the original question paper for the diagrams.)

Question 11

Consider the following data obtained from a survey conducted in a colony. (3 Marks)

Draw a double bar graph by choosing a suitable scale.

(Graph not drawn here. Please draw on paper with scale: 1 unit = 100 people on y-axis, sports on x-axis.)
