### (Prelims) IAS General Studies – 1998 (Part 3)

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

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

A   B   C    D
(a)   4    3    2    6
(b)   4    5    1    6
(c)   2    3    4    5
(d)   1    6    2    3

33. Bharat Ratna was awarded in 1997 to
(a) Dr. Homi Bhabha (Posthumous)
(b) Former President R. Venkataraman
(c) Satyajit Ray (Posthumous)
(d) Dr. Abdul Kalam

Ans: d

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.

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.
