CBSE CLASS 7 MATHEMATICS WORKSHEETS/Part 5/Yearly Examination.
Fill in the blanks:

1. 25% = ———— (as fraction in simplest form)
2. The coefficient of y in 2x – 3y +5z +6 is —————-
3. The value of the expression 3x – y, when x = 2, y= 0 is —————
4. 2:5:: 6: x, the value of x is ————–
5. The area of a parallelogram is 63 sq.cm. If the base is 9 cm, its height is ——-
6. The price of a toy car decreased from 400 rupees to 300 rupees. Find the percentage of decrease?
7. List four rational numbers between -3 and -1
8. The diameter of a tyre is 70 cm. Find the distance covered by it in 10 rounds?
9. Add 4x +6xy –y and 5y – 3xy -3x
10. Find the value of k, if 4x – 3k = -12, when x = 0.

1. ¼
2. -3
3. 6
4. 15
5. 7 cm
6. Percentage decrease = (Amount of change/Original amount) x 100
= (100/400) x 100
= 25%
7. To find rational numbers between -3 and -1, we can convert these numbers to like fractions as -3 = -30/10 and -1 = -10/10.
So the four rational numbers between -3 and -1 are -11/10, -12/10, -13/10 and -14/10.
8. Given diameter = 70 cm, radius = 35 cm.
Distance covered = Circumference of a circle = 2 x 3.14 x 35 = 219.8 cm
Distance covered in 10 rounds = 219.8 x 10 = 2198 cm
9. 4x + 6xy – y + (5y – 3xy – 3x) = 4x -3x + 6xy – 3xy – y + 5y
= x + 3xy + 4y
10. When x = 0, 4x – 3k = -12
4 x 0 – 3k = -12
0 – 3k = -12
k = -12/-3 = 4.
