<\/span>Ans. (a)<\/strong><\/span><\/h3>\n\n\n\nFrom locations I and III, it can be observed that the traffic volume is the same. As the average noise level is also the same for both locations, the differing factor is the percentage of heavy vehicles. Therefore, it is evident that the percentage of heavy vehicles directly impacts the noise pollution level.<\/p>\n\n\n\n
<\/span>Q3. The variations in temperatures form 0\u00b0C to 100\u00b0C with respect to time of two liquids P, Q are shown in the graph given below (1995)<\/strong><\/span><\/h2>\n\n\n\nWhich one of the following statements is correct?<\/em><\/p>\n\n\n\n(a) During heating, liquid P remained hotter than liquid Q throughout <\/p>\n\n\n\n

<\/span>Ans. (d)<\/strong><\/span><\/h3>\n\n\n\nAs depicted in the graph, it’s evident that Q reaches a temperature of 100\u00b0C more rapidly compared to P.<\/p>\n\n\n\n
<\/span>Q4. The price fluctuations of 4 scrips in a stock market in the four quarters of a year are shown in the table below.

(b) Investor 1 has made the best investment <\/p>\n\n\n\n
(c) Investor 2 suffered a net loss during the year <\/p>\n\n\n\n
(d) Investor 3 suffered a net loss during the year<\/p>\n\n\n\n
<\/span>Ans. (b)<\/strong><\/span><\/h3>\n\n\n\nAccording to the portfolios table, it is apparent that investor 1 has allocated a larger portion of their investment in scrip D, which exhibits the least decrease. This results in the best average investment performance by investor 1 compared to the others.<\/p>\n\n\n\n
<\/span>Q5. The following table shows the percentage distribution of revenue expenditure of Government of India in 1989-90 and 1994-95.

(b) spend more and more on interest payments <\/p>\n\n\n\n
(c) reduce expenditure on subsidies<\/p>\n\n\n\n
(d) spend more and more as grants-in-aid to State government\/Union Territories<\/p>\n\n\n\n
<\/span>Ans. (b)<\/strong><\/span><\/h3>\n\n\n\nBased on the data illustrating revenues and expenditures of the Indian Government, it appears that the Indian economy is facing challenges, particularly due to the increasing debt payments. The rising burden of debt payments leaves less financial resources available for other purposes.<\/p>\n\n\n\n
<\/span>Q6. The following figure represents sales (in thousands), over the period 1978 to 1983. (1996)<\/strong><\/span><\/h2>\n\n\n\nThe sales in 1981 exceeded that in 1979 by<\/em><\/p>\n\n\n\n(a) \u20b9100<\/p>\n\n\n\n

(d) \u20b91000000<\/p>\n\n\n\n
<\/span>Ans. (c)<\/strong><\/span><\/h3>\n\n\n\nGiven the sales in the year 1979 are 320,000 and the sales in the year 1981 are 420,000. Therefore, the required difference is calculated as 420,000 – 320,000, resulting in a difference of 100,000.<\/p>\n\n\n\n
<\/span>Q7. The given pie charts show the proportion of literates and illiterates in a country, in the year 1970 and 1990, (1996)<\/strong><\/span><\/h2>\n\n\n\nand also the proportion of males (M) and females (F) among the literates. Which one of the following statements can be said to be true beyond any doubt?<\/p>\n\n\n\n
(a) In 1970 half of the illiterates were women (females) <\/p>\n\n\n\n
(b) The proportion of literate males to the total population of males remained the same over the years <\/p>\n\n\n\n
(c) Male literacy did not improve over this period <\/p>\n\n\n\n
(d) The ratio of female literates to male literates improved significantly over this period<\/p>\n\n\n\n
<\/span>Ans. (d)<\/strong><\/span><\/h3>\n\n\n\nThe chart clearly illustrates an improvement in the ratio of female literates to male literates over time.<\/p>\n\n\n\n

For a height of 1.60 m, the ratio is 7\/6 = 1.16.<\/p>\n\n\n\n
For a height of 1.65 m, the ratio is 15\/14 = 1.07.<\/p>\n\n\n\n
For a height of 1.71 m, the ratio is 6\/5 = 1.2<\/p>\n\n\n\n
Hence, the ratio of students in section A to B is maximum for the category of height 1.55 m.<\/p>\n\n\n\n
