33. If the equations x - 2y = 3 and 2x + by = 6 represent the same line, then the value of b is

(1) 4
(2) -4
(3)-2
(4) None of these

Correct Answer: (2) -4

Solution:a₁x+b₁y=c₁, and a₂x + b₂ y = c₂, will be

coincident if = a₁/a₂ = b₁/b₂ = c₁/c₂

Here, a₁ = 1, b₁= - 2, c₁= 3

a₂ = 2, b₂ = b, c₂ = 6

∴ 1/2 = - 2/b

⇒ b = - 4

35. In ∆АВС, AB = 6√3 cm, AC 12 cm and BC = 6 cm, then ∠B is

(1) 120°
(2) 60°
(3) 90°
(4) 45°

Correct Answer: (3) 90°

Solution:AB² + BC² = (6√3)² + (6)²

⇒ AB² + BC² = 36 * 3 + 36

=108+36 = 144

⇒AB² + BC² = 12² = AC²

⇒ B = 90°

36. The sum of digits of two digit number is 9. Also, nine times this number is twice the number obtained by reversing the order of the digits of the number. Then the number is

(1) 18
(2) 81
(3) 36
(4) None of these

Correct Answer: (1) 18

Solution:Let the number be 10x + y.

According to the question,

x + y = 9 ....... (i)

and, 9 (10x + y) = 2(10y + x)

⇒ 90x + 9y = 20y + 2x

⇒ 90x - 2x + 9y - 20y = 0

⇒ 88x - 11y = 0

⇒8x - y = 0 ...... (ii)

Adding equations (i) and (ii),

9x = 9

⇒ x = 1

From equation (i),

y = 9 - 1 = 8

∴Number = 10 + 8 = 18
