(a) (3 + √7)

(b) (3 – √7)

(c) (3 + √7) (3 – √7)

(d) 3√7

Answer: (c) (3 + √7) (3 – √7)

Explanation: If we solve, (3 + √7) (3 – √7), we get;

(3 + √7) (3 – √7) = 32 – (√7)2 = 9 – 7 = 2 [By a2 – b2 = (a – b) (a + b)] - The largest number that divides 70 and 125, which leaves the remainders 5 and 8, is:

(a) 65

(b) 15

(c) 13

(d) 25

Answer: (c) 13

Explanation: 70 – 5 = 65 and 125 – 8 = 117

HCF (65, 117) is the largest number that divides 70 and 125 and leaves remainder 5 and 8.

HCF (65, 117) = 13 - The decimal expansion of the rational number 23/(22 . 5) will terminate after

(a) one decimal place

(b) two decimal places

(c) three decimal places

(d) more than 3 decimal places

Answer: (b) two decimal places

Explanation:

23/(22 . 5) = (23 × 5)/(22 . 52) = 115/(10)2 = 115/100 = 1.15

Hence, 23/(22 . 5) will terminate after two decimal places. - Using Euclid’s division algorithm, the HCF of 231 and 396 is

(a) 32

(b) 21

(c) 13

(d) 33

Answer: (d) 33

Explanation:

396 > 231

Using Euclid’s division algorithm,

396 = 231 × 1 + 165

231 = 165 × 1 + 66

165 = 66 × 2 + 33

66 = 33 × 2 + 0 - n² – 1 is divisible by 8, if n is

(a) an integer

(b) a natural number

(c) an odd integer

(d) an even integer

Answer: (c) an odd integer

Explanation:

We know that an odd number in the form (2Q + 1) where Q is a natural number ,

so, n² -1 = (2Q + 1)² -1

= 4Q² + 4Q + 1 -1

= 4Q² + 4Q

Substituting Q = 1, 2,…

When Q = 1,

4Q² + 4Q = 4(1)² + 4(1) = 4 + 4 = 8 , it is divisible by 8.

When Q = 2,

4Q² + 4Q = 4(2)² + 4(2) =16 + 8 = 24, it is also divisible by 8 .

When Q = 3,

4Q² + 4Q = 4(3)² + 4(3) = 36 + 12 = 48 , divisible by 8

It is concluded that 4Q² + 4Q is divisible by 8 for all natural numbers.

Hence, n² -1 is divisible by 8 for all odd values of n. - Fifteen solid spheres are made by melting a solid metallic cone of base diameter 2cm and height 15cm. The radius of each sphere is:

(a) ½

(b) ¼

(c) 1/3√2

(d) 1/3√4

Answer: (d) 1/3√4

Explanation: Volume of 15 spheres = Volume of a cone

15 x (4/3) π r3 = ⅓ πr2h

5×4 π r3 = ⅓ π 12(15)

20r3 = 5

r3 = 5/20 = ¼

r = 1/3√4 - The radius of the top and bottom of a bucket of slant height 35 cm are 25 cm and 8 cm. The curved surface of the bucket is:

(a) 4000 sq.cm

(b) 3500 sq.cm

(c) 3630 sq.cm

(d) 3750 sq.cm

Answer: (c) 3630 sq.cm

Explanation: Curved surface of bucket = π(R1 + R2) x slant height (l)

Curved Surface = (22/7) x (25 + 8) x 35

CSA = 22 x 33 x 5 = 3630 sq.cm. - The area of a sector of a circle with radius 6 cm if the angle of the sector is 60°.

(a) 142/7

(b) 152/7

(c) 132/7

(d) 122/7

Answer: (c) 132/7

Explanation: Angle of the sector is 60°

Area of sector = (θ/360°) × π r2

∴ Area of the sector with angle 60° = (60°/360°) × π r2 cm2

= (36/6) π cm2

= 6 × (22/7) cm2

= 132/7 cm2 - In a circle of radius 21 cm, an arc subtends an angle of 60° at the centre. The length of the arc is;

(a) 20cm

(b) 21cm

(c) 22cm

(d) 25cm

Answer: (c) 22cm

Explanation: Length of an arc = (θ/360°) × (2πr)

∴ Length of an arc AB = (60°/360°) × 2 × 22/7 × 21

= (1/6) × 2 × (22/7) × 21

Or Arc AB Length = 22cm - In a circle of radius 14 cm, an arc subtends an angle of 30° at the centre, the length of the arc is

(a) 44 cm

(b) 28 cm

(c) 11 cm

(d) 22/3 cm

Answer: (d) 22/3 cm

Explanation:

Given, radius = r = 14 cm

Length of arc = (2πrθ)/360

= 2 × (22/7) × 14 × (30/360)

= 22/3 cm
