2. If A = {1,2,3,4,5,7,9,11}, find n(A).

3. Write all the subsets of A = {a, b}.

4. If A={1, 2, 6} and B={2, 3, 4} , find A∪B.

5. If A = {6, 7, 8, 9} and B={8, 10, 12}, find A Δ B.

6. Draw a Venn diagram similar to one at the side and shade the region representing the following sets

(A – B)′

7. Let A = {b, d, e, g, h} and B = {a, e, c, h}. Verify that n(A – B) = n(A) – n(A∩B).

8. If n(A) = 4, find n[P(A)].

9. Using the given Venn diagram, write the elements of

11. Find any three rational numbers between $\frac { -7 }{ 11 }$and $\frac { 2 }{ 11 }$

12. Without actual division, classify the decimal expansion of the following numbers as terminating or non - terminating and recurring.
(i) $\frac { 13 }{ 64 }$
(ii) $\frac { -71 }{ 125 }$
(iii) $\frac { 43 }{ 375 }$
(iv) $\frac { 31 }{ 100 }$

13. Write the coefficient of xand x in each of the following polynomials ${ \pi x }^{ 2 }-x+2$

14. Find the zeros of the polynomial in each of the following: q(y) = 2y-3.

15. Divide x3-4x2+6x by x, where,  x≠0

16. Find the number of zeros of the following polynomials represented by their graphs.

17. Find the complement of the following angles (1°= 60′ minutes, 1′ = 60′′ seconds)
62°32′

18. Find the supplement of the following angles.
Right angle

19. Find the value of x

20. Identify which ones are trapeziums and which are not.

21. Objective: To construct a perpendicular bisector of a line segment using paper folding.
Procedure: Make a line segment on a paper by folding it and name it as PQ. Fold PQ to such a way that P falls on Q and thereby creating a crease RS. This line RS is the perpendicular bisector of PQ.

22. The radius of a circle 15 em and the length of one of its chord is 24 cm. Find the distance of the chord from the centre.

23. In which quadrant does the following points lie? (3,–8)

24. In which quadrant does the following points lie?(–7, 3)

25. Plot the following points in the coordinate plane. Join them in order. What type of geometrical shape is formed? (0,0) (–4,0) (–4,–4) (0,–4)
