31. LMNOP, is semicircle with center at R and diameter LP, LSR and RQP are also semicircles with centers at T and U and diameters LR= RP =1 /2 LP. The ratio of perimeters of LMNOP and LSRQP us
(a) 0.75: 1
(b) 1:1
(c) 1 : 0.75
(d) 1.25: 1

Ans: b

• Radius of LMNOP = r, Radius of LSR = r/2
• Perimeter of LMNOP = pi*r + 2*r
• Perimeter of LSRQP = 2 ( Perimeter of LSR) = 2( pi*r/2 + r)
• Ratio = 1: 1

34. Which of the following statements are true about the Indian born woman astronaut Kalpana Chawla ?
1. She was born in Karnal.
2. She flew on board the shuttle flight STS – 87.
3. She was trained at the Kennedy Space Centre.
4. She did a space-walk to retrieve the Spartan Satellite.
Select the correct answer using the codes given below
(a) 1 and 2
(b) 2 and 3
(c) 1, 2 and 3
(d) 1, 2 and 4

35. A man purchases two clocks A and B at a total cost of Rs. 650. He sells A with 20% profit and B at a loss of 25% and gets the same selling price for both the clocks. What are the purchasing price of A and B respectively
(a) Rs. 225 ; Rs. 425
(b) Rs. 250 ; Rs. 400
(c) Rs. 275 ; Rs. 375
(d) Rs. 300 ; Rs. 350

Ans: b

• x + x(20/100) = (650 – x) (1- 25/100) = > x = 250, 650 – x = 400
  
  36. A fuse is used in main electric supply as a safety device. Which one of the following statements about the fuse is correct ?
  (a) It is connected in parallel with the main switch
  (b) It is made mainly from silver alloys
  (c) It must have a low melting point
  (d) It must have a very high resistance

Ans: c

• A fuse is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, interrupting the circuit that it connects. Short circuits, overloading, mismatched loads, or device failure are the prime reasons for excessive current. Fuses are an alternative to circuit breakers.
• The fuse element is made of zinc, copper, silver, aluminum, or alloys to provide stable and predictable characteristics.

Directions :– The following fourteen items consist of two statements, one labelled as ‘Assertion A and the other labelled as ‘Reason R’. You are to examine these two statements carefully and decide if the Assertion A and the Reason R are individually true and if so, whether the Reason is a correct explanation of the Assertion.

Ans: b

39. Assertion A : At first the Turkish administration in India was essentially military.
Reason R         : The country was parcelled out as ‘Iqtas’ among leading military leaders.

Ans: a

40. Assertion A : According to Asoka’s edicts social harmony among the people was more
important than religious devotion.
Reason R          : He spread ideas of equity instead of promotion of religion.

Ans: b

41. Assertion A : The temperature of a metal wire rises when an electric current is passed
through it.
Reason R         : Collision of metal atoms with each other releases heat energy.

Ans: a

42. Assertion A : The Khilafat movement did bring the urban Muslims into the fold of the.
National Movement.
Reason R         : There was a predominant elements of anti-imperialism in both the National
and Khilafat Movement.

Ans: a

43. Assertion A : Phenyl is used as a household germicide. Phenyl is a phenol derivative and
phenol is an effective germicide.
Reason R          : Phenyl is a phenol derivative and phenol is an effective germicide

Ans: a

• Phenol is germicidal in strong solution, and inhibitory in weaker ones. It is used as a “scrub” for preoperative hand cleansing, and in the form of a powder as an antiseptic baby powder. Also used in mouthwashes and throat lozenges, it has a painkilling effect, as well as an antiseptic one.
