4. If 2 is a zero of polynomial f(x) = ax²-3(a-1) x-1, then value of a is

(1) 5/2
(2) -2/5
(3) -5/2
(4) None of these

Correct Answer: (1) 5/2

Solution:f(x) = ax²-3(a-1) x-1

2 is a root of polynomial f(x).

∴ f(2) = 0

⇒ a * (2)² - 3 (a-1) * 2 - 1

= 0

⇒ 4a - 6a + 6 - 1 = 0

⇒ - 2a + 5 = 0

⇒ 2a = 5 ⇒ a = 5/2

5. 5000 years old Indus valley civilization, found in the present day________ District.

(1) Ranchi
(2) Hisar
(3) Kurukshetra
(4) Angeerasa

Correct Answer: (2) Hisar

6. An object 4 cm in size, is placed at 20 cm in front of a concave mirror of focal length 10 cm. At what distance from the mirror should a screen be placed in order to obtain a sharp image?

(1) 20 cm from the mirror
(2) 10 cm from the mirror
(3) 20/3 cm from the mirror
(4) 10/3 em from the mirror

Correct Answer: (1) 20 cm from the mirror

Solution:Focal length, f = 10cm

Object distance, u = 20cm

Image distance, v = ?

h₀= 4cm

Mirror formula,

1/v + 1/v = 1/f

1/f - 1/u = 1/v

⇒ 1/- 10 + 1/20 = 1/v

= -2+1/20 = 1/v ⇒ v = - 20cm

m = -v/u = h₁/h₀

⇒- (- 20)/- 20 = h₁ /4

h₁ = - 4cm

This to get image of object sharp, it has to be placed at 20cm.

Size of image is 4 cm.

7. Find the word which is different from the other 3 options given below.

(1) Mathematics
(2) Arithmetic
(3) Algebra

(1) Tessay Thomas
(2) Mangala Mani
(3) Nandini Harinath
(4) Anuradha T. K.

Correct Answer: (2) Mangala Mani

Solution:Indian Space Research Organisation (ISRO)'s first wom-an scientist Mangala Mani has scripted a history by spending 403 days in Antarctica. 56-year-old, Mani, was part of an expedition team which went to India's research station, Bharati, in November 2016.

9. New States come to exist through union, consolidation, confederation etc. Here confederation refers to

(2) Form of Union where States are strong and Centre is weak
(1) Form of Union where Centre is strong and States are weak
(3) Some States have strong power and Centre is also strong
(4) Equal power sharing be-tween Centre and States

Correct Answer: (2) Form of Union where States are strong and Centre is weak

Solution:A confederation (also known as a confederacy or league) is a union of sovereign states, united for purposes of common action often in relation to other states. n a Confederation, the federal government is accountable to the member states, who are the ultimate authority.

10. Find the number which is not like the other 3 numbers.

(1) 3/21
(2) 4/14
(3) 6/21
(4) 16/56

Correct Answer: (2) 4/14

Solution:4/14 = (2 * 2)/(2 * 7) = 2/7

6/21 = (2 * 3)/(7 * 3) = 2/7

16/56 = (2 * 8)/(7 * 8) = 2/7

But, 3/21 = 1/7
