Explanation:     In (1) there is no information about joby salary and in (2) there is no information about manu salary; thus neither statement alone is sufficient, and the answer must thethird or fifth choice. Since (1) and (2) together give only the percentage             increases insalary, it cannot be determined which person received the greater dollar increase.Therefore, (1) and (2) together are not sufficient, and the best answer is the last choice.

5. The symbol ∇ represents one of the following operations: addition, subtraction,multiplication, or division. What is the value of 3 ∇ 2 ?   (1) 0 + 1 = 1<p> </p>   (2) 1 - 0 = 1        A.Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.        B.Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.        C.BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.        D.EACH statement ALONE is sufficient

Explanation:     Since 0 + 1 = 1, 0 - 1 = -1, 0 × 1 = 0, and 0 ÷ 1 = 0, it follows from (1) that ∇ represents addition, so the value of 3 ∇ 2 can be determined. Hence, (1) alone is sufficient.Since 1 + 0 = 1, 1 - 0 = 1, 1 × 0 = 0, and 1 ÷ 0 is undefined, it             follows from (2) that ∇ could represent either addition or subtraction, so that 3 ∇ 2 could equal 5 or 1. Thus, (2) alone is not sufficient. The best answer is the first choice

21.Read the following passage and answer the questions: To those who do listen, the desert speaks of things with an emphasis quite different from that of the shore, the mountain, the valley or the plains, whereas these invite action and suggest limitless opportunity and exhaust less resources, the implications and the mood of the desert are something different. For one thing , the desert is conservative not radical. It is more likely to provide awe than to invite conquest. The heroism which it encourages is the heroism of endurance, not that of conquest. It brings man up against this limitation, turns him upon himself and suggests values which more indulgent regions suppress. Sometimes it includes contemplation in men who have never contemplated before : And of all the answers to the question- what is a desert good for - 'contemplation' is perhaps the best. The last half of my life was spent at one of those painful epochs of human history, during which world was getting worse and past victories which had seemed to be definitive have turned out to be only temporary. When I was young , Victorian optimism was taken for granted. It was thought that freedom and prosperity would spread gradually  throughout the world through an orderly process, and it was hoped that cruelty ,tyranny and injustice would continually diminish. Hardly anyone thought of the nineteenth century as a brief interlude between past and future barbarism. In order to receive the desert's message ,the beholder needs to be?        A.contemplation        B.Indolence        C.Heroic Endeavor        D.Adventurous Spirit

26. Read the following passage and answer the questions: Work expands so as to fill the time available for its completion .The general recognition of this fact is shown in the proverbial phrase,' It is the busiest man who has time to spare'. Thus, an elderly lady at leisure can spend the entire day writing a post card to her niece. An hour will be spent in writing a postcard , another hunting for spectacles, half an hour to search for the address ,an hour and a quarter in composition and twenty minutes in deciding whether or not to take an umbrella when going to the pillar box in the street. The total effort that could occupy a busy man for three minutes, all told may in this fashion leave another person completely exhausted after a day of doubt ,anxiety and toil.   Accidents on roads can be prevented, provided the quality of roads is improved and the drivers are instructed in safety rules which they must follow for their own protection. It is also necessary that the illumination on the roads is adequate so as to prevent accidents at night. The surprisingly abundant life of the Indian Ocean is confined to the upper layers; the deeper and especially the bottom waters are devoid of oxygen and are often permeated with hydrogen sulphide. It is not luck but labour that makes man. Luck, says an American Writer, is ever waiting for something to turn up; labour with keen eyes and strong will always turns up something.

Luck slips downwards to self-indulgence; labour strides upwards and aspires to independence. The conviction therefore, is extending that diligence is the mother of good luck.
