SECTION-A [40 Marks]
(Answer all questions from this Section.)

Question 1

(a) Ranbir borrows Rs. 20,000 at 12% per annum compound interest. If he repays Rs. 8400 at the end of the first year and Rs. 9680 at the end of the second year, find the amount of loan outstanding at the beginning of the third year. [3]

The die is thrown once. What is the probability of getting
(i) a positive integer.
(ii) an integer greater than -3.
(iii) the smallest integer. [4]

Question 2

(b) Shahrukh opened a Recurring Deposit Account in a hank and deposited Rs. 800 per month for if years. If he received Rs. 15,084 at the time of maturity, find the rate of interest per annum. [3]
(c) Calculate the ratio in which the line joining A (-4, 2) and B(3, 6) is divided by point P(x, 3). Also find (i) x (ii) Length of AP. [4]

Hence, rate of interest = 6% p.a.
(c) Let P(x, 3) divide the line segment joining the points A (-4, 2) and B (3, 6) in the ratio k : 1

Question 3

(a) Without using trigonometric tables, evaluate sin2 34° + sin2 56°+ 2 tan 18° tan 72°- cot2 30° [3]
(b) Using the Remainder and Factor Theorem, factorise the following polynomial: x3 + 10x2 – 37x + 26. [3]
(c) In the figure given below, ABCD is a rectangle. AB = 14 cm, BC = 7 cm. From the rectangle, a quarter circle BFEC and a semicircle DGE are removed.
Calculate the area of the remaining piece of the rectangle. (Take π = $\frac { 22 }{ 7 }$[4]

On dividing x3 + 10x2 – 37x + 26 by x – 1, we get x2 + 11x – 26 as the quotient and remainder = 0.

Question 4

(a) The numbers 6, 8, 10, 12, 13 and x are arranged in an ascending order. If the mean of the observations is equal to the median, find the value of x. [3]
(b) In the figure, ∠DBC = 58°. BD is a diameter of the circle. Calculate :
(i) ∠BDC         (ii) ∠BEC            (iii) ∠BAC
(c) Using graph paper to answer the following questions. (Take 2 cm – 1 unit on both axis)

(iii) B’ is the image of B when reflected in the line AA’. Write the coordinates of B’.
(iv) Write the geometric name of the figure ABAB’.
(v) Name a line of symmetry of the figure formed. [4]

(b) In ∆ BCD; ∠DBC = 58°
(i) ∠BCD = 90° (Angle in the semicircle as BD is diameter)
∴ ∠DBC + ∠BCD + ∠BDC = 180°
⇒ 58°+ 90° +∠BDC = 180°
⇒ ∠BDC = 180° – (90° + 58°)
= 180°-148°
= 32° Ans.

(ii) ∠BEC + ∠BDC = 180° ( ∵BECD is a cyclic quadrilateral)

∠BEC = 180°- ∠BDC = 180°-32°
∠BEC = 148°

(iii) ∠BAC = ∠BDC (Angle of same segment are equal)
∠BAC = 32°

(c) (i) See Graph.

(ii) Coordinate of A’ = (4, 2)
