32. Consider the following pie graph depicting budget of a family:

How many degrees difference be there in the central angle of the sector for saving and miscellaneous expenses?

Correct Answer: (b) 36°
Solution:Central angle for saving = 20/100 × 360 = 72°

Central angle for miscellaneous = 10/100 × 360 = 36°

Required difference = 72 - 36 = 36°

33. 3G and 4G are wireless technologies, which are supposedly faster, more secure and reliable. Present day 3G technology is capable of handling data around 2 Megabits per second (1.8 - 2.5 GHz frequency band). What speed is expected from new 4G technology?

Correct Answer: (c) 100 Megabits-1 Gigabit per second (2-8 GHz frequency band)
Solution:The 4G wireless cellular standard was defined by the International Telecommunication Union (ITU) and specifies the key characteristics of the standard, including transmission technology and data speeds.

Each generation of wireless cellular technology has introduced increased bandwidth speeds and network capacity. 4G users get speeds of up to 100 Megabits (Mbps), while 3G only promised a peak speed of 14 Mbps. Thus, option (c) is the correct answer.

34. The Kuroshio is a north flowing Ocean current on the west side of the North Pacific Ocean. Which one among the following statements regarding this is not correct?

The warm water of the Kuroshio Current sustains the coral reefs of Japan. It originates from the North Equatorial Current on the east coast of the Philippines. Thus, option (d) is incorrect and it is the answer.

35. Consider the following information :

Which book is between Mathematics book and English book?

Correct Answer: (d) Civics
Solution:The following will be the sequence of books piled upon one another.

Physics

Maths

Civics

English

History

Commerce

Therefore, between Mathematics and English books lies in the Civics book. So, (d) is the correct option.

36. Pesticide treadmill refers to :

Correct Answer: (b) Increase in doses of pesticides to prevent the resurgence of pests that were being controlled
Solution:The term pesticide treadmill describes the phenomenon whereby pesticide use prevents any natural form of control from taking place, thereby resulting in the need for repeated, routine applications of pesticide. The pesticide treadmill is said to escalate when the control of one pest provides a window of opportunity for other pests and the need for further chemicals. In short, there is an increase in doses of pesticides to prevent the resurgence of pests that were being controlled. Thus, option (b) is the correct answer.
