1. If the numbers 2n – 1, 3n + 2 and 6n – 1 are in A.P., then find n and hence find the numbers.
Answer : Let 2n – 1, 3n + 2 and 6n – 1 are in A.P.
∴ (3n + 2) – (2n – 1) = (6n – 1) – (3n + 2)
⇒ n + 3 = 3n – 3 ⇒ 6 = 2n ⇒ n = 3
∴ Numbers are : 2(3) –1 = 5, 3(3) +2 = 11 and 6(3) –1 = 17.

2. A solid iron rectangular block of dimensions 4.4 m, 2.6 m and 1 m is recast into a hollow cylinder of internal radius 30 cm and thickness 5 cm. Find the length of the pipe.
Answer : Volume of iron = (440 × 260 × 100) cm3
Internal radius of the pipe = 30 cm
External radius of the pipe = (30 + 5)cm = 35 cm
Let the length of the pipe be h cm.
Volume of iron in the pipe = (External volume) – (Internal volume)

3. Find k so that the quadratic equation (k + 1)x2 − 2(k + 1)x + 1 = 0 has equal roots.
Answer : We have (k + 1)x2 – 2(k + 1)x + 1 = 0
Comparing with Ax2 + Bx + C = 0 we get A = (k + 1),B,= -2(k+ 1), C= 1
If roots are equal, then D = 0, i.e. B2 – 4AC = 0
⇒ B2 = 4AC
⇒ 4(k+ 1)2 = 4(k+ 1)
⇒ k2 + 2k + 1 = k + 1
⇒ k2 + k = 0
⇒ k(k + 1) = 0
⇒ k = 0, – 1
Since k = – 1 does not satisfy the equation, thus k = 0

7. Draw a circle of radius 3.5 cm. Draw two tangents to the circle which are perpendicular to each other.
Answer : Steps of construction :
Step-I : Draw a circle of radius 3.5 cm with centre O.
Step-II : Draw a diameter AB.
Step-III : Construct ∠AOP = 90°.
Step-IV : At P and B, draw PY ⊥ OP and BX ⊥ OB.
Step-V : Let PY and BX intersect at D.
Hence, DB and DP are required tangents to the circle perpendicular to each other.

8. At a point A, 20 metres above the level of water in a lake, the angle of elevation of a cloud is 30°. The angle of depression of the reflection of the cloud in the lake, at A is 60°. Find the distance of the cloud from A.
Answer : Let DE be the level of water and cloud be at position B which is h m above the level of water and reflection of cloud be at F and AC = DE = x m.
∴ BC = (h – 20)m, CF = (h + 20) m

A hollow cylindrical pipe is made up of copper. It is 21 dm long. The outer and inner diameters of the pipe are 10 cm and 6 cm respectively. Find the volume of copper used in making the pipe.
Answer : Volume of copper used in making the pipe is equal to the difference of volume of external cylinder and volume of internal cylinder.
Height of cylindrical pipe, h = 21 dm = 210 cm
External Radius, R = 10/2 = 5 cm
Internal Radius, r = 6/2 = 3 cm

12. In the given fig., ΔABC is circumscribed touching the circle at P, Q, R if AP = 4 cm, BP = 6 cm, AC = 12 cm, then find radius of circle.
Answer : We have, AP = 4 cm, BP = 6 cm and AC = 12 cm
Since the length of tangents drawn from an external point to a circle, are equal.
∴ AP = AR ⇒ AR = 4 cm
Also, BP = BQ ⇒ BQ = 6 cm
and CR = CQ ⇒ CR = AC – AR = (12 – 4) cm = 8 cm
Now, BC = BQ + CQ = (6 + 8) cm = 14 cm
