So, statement I alone is not sufficient.<\/p>\n (II) :\u00a0In each column ,number of trees are even, => number of rows are even in number<\/p>\n Again, we do not know\u00a0the exact value. So, statement II alone is not sufficient.<\/p>\n Combining above statements, we still do not know the\u00a0exact number of columns and rows. So, statement I and II together are not sufficient.<\/p>\n => Ans – (D)<\/p>\n Question 4:\u00a0<\/b>What is the rate of interest? a)\u00a0If the data in statement I alone are sufficient to answer the question, while the data in statement<\/p>\n b)\u00a0If the data in statement II alone are sufficient to answer the question, while the data in statement<\/p>\n c)\u00a0If the data either in statement I alone or in statement II alone are sufficient to answer the question<\/p>\n d)\u00a0If the data given in both statements I and II together are not sufficient to answer the question and<\/p>\n e)\u00a0If the data in both statements I and II together are necessary to answer the question.<\/p>\n 4)\u00a0Answer\u00a0(C)<\/strong><\/p>\n Solution:<\/b><\/p>\n Let rate of interest = $R \\%$<\/p>\n I : P = Rs. 25,000 and time period = 2 years<\/p>\n => $S.I. = \\frac{P \\times R \\times T}{100}$<\/p>\n = $\\frac{25000 \\times R \\times 2}{100} = 500 R$<\/p>\n Interest obtained from compound interest = $P [(1 + \\frac{R}{100})^T – 1]$<\/p>\n => $(500R + 250) = 25000 [(1 + \\frac{R}{100})^2 – 1]$<\/p>\n => $250 (2R + 1) = 25000 [(1 + \\frac{R}{100})^2 – 1]$<\/p>\n => $2R + 1 = 100 (1 + \\frac{R^2}{100^2} + \\frac{2 R}{100} – 1)$<\/p>\n => $2R + 1 = \\frac{R^2}{100} + 2R$<\/p>\n => $R^2 = 100 \\times 1 = 100$<\/p>\n => $R = \\sqrt{100} = 10 \\%$<\/p>\n Thus, statement I alone is sufficient.<\/p>\n II : Let original sum = simple interest = $Rs. P$ and time period = 10 years<\/p>\n => $S.I. = \\frac{P \\times R \\times T}{100}$<\/p>\n => $P = \\frac{P \\times R \\times 10}{100}$<\/p>\n => $R = \\frac{100}{10} = 10 \\%$<\/p>\n Thus, statement II alone is also sufficient.<\/p>\n Thus, either statement alone is sufficient.<\/strong><\/p>\n Question 5:\u00a0<\/b>What is the area of the circle ? a)\u00a0If the data in statement I alone are sufficient to answer the question, while the data in statement<\/p>\n b)\u00a0If the data in statement II alone are sufficient to answer the question, while the data in statement<\/p>\n c)\u00a0If the data either in statement I alone or in statement II alone are sufficient to answer the question<\/p>\n d)\u00a0If the data given in both statements I and II together are not sufficient to answer the question and<\/p>\n e)\u00a0If the data in both statements I and II together are necessary to answer the question.<\/p>\n 5)\u00a0Answer\u00a0(C)<\/strong><\/p>\n Solution:<\/b><\/p>\n Let radius of the circle = $r$ cm<\/p>\n I : Perimeter = $2 \\pi r = 88$<\/p>\n => $2 \\times \\frac{22}{7} \\times r = 88$<\/p>\n => $r = 88 \\times \\frac{7}{44} = 14$ cm<\/p>\n $\\therefore$ Area = $\\pi r^2 = \\frac{22}{7} \\times (14)^2$<\/p>\n = $22 \\times 2 \\times 14 = 616 cm^2$<\/p>\n Thus, statement I alone is sufficient.<\/p>\n II : Diameter = 28 cm<\/p>\n => Radius, $r = \\frac{28}{2} = 14$ cm<\/p>\n $\\therefore$ Area = $\\pi r^2 = \\frac{22}{7} \\times (14)^2$<\/p>\n = $22 \\times 2 \\times 14 = 616 cm^2$<\/p>\n Thus, statement II alone is sufficient.<\/p>\n Thus, either statement alone is sufficient.<\/strong><\/p>\n Instructions<\/b><\/p>\n Each of the questions below consists of a question and two statements numbered I and II given below it.

There is no information about position of F and J.<\/p>\n Thus, II alone is not sufficient.<\/p>\n Combining\u00a0I & II : F is not an immediate neighbor of I.<\/p>\n => F will sit between G and E.<\/p>\n => G is sitting to the immediate left of F.<\/p>\n Thus, I & II together are sufficient.<\/strong><\/p>\n Question 7:\u00a0<\/b>How many persons are there in a straight line who are facing North ? a)\u00a0if the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.<\/p>\n b)\u00a0if the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.<\/p>\n c)\u00a0if the data either in Statement I alone or in Statement II alone are sufficient to answer the question.<\/p>\n d)\u00a0if the data even in both Statements I and II together are not sufficient to answer the question.<\/p>\n e)\u00a0if the data in both Statements I and II together are necessary to answer the question.<\/p>\n 7)\u00a0Answer\u00a0(B)<\/strong><\/p>\n Solution:<\/b><\/p>\n I : B is standing at the left end and\u00a0T is standing at the second position from the left end of the line<\/p>\n => T is to the immediate right of B.<\/p>\n Also, 2 persons are standing between A\u00a0and T, => A is standing at the 5th position from left end.<\/p>\n A is also immediate neighbor of L, who sits in the middle.<\/p>\n => L is at either 4th position from left end, which means total number of members in the line = 7<\/p>\n Or, L is at 6th position from left end,\u00a0which means total number of members in the line = 11<\/p>\n Thus, I alone is not sufficient.<\/p>\n II :\u00a0J is standing at the second position from the right end of the line and five persons are standing between J and F<\/p>\n => F is standing at 8th position from the right end.<\/p>\n There are two persons between F and K and K is at one of the extreme ends of the line.<\/p>\n => K is at left end, and F is at 4th position from the left end of the line.<\/p>\n => Total members in the line = 8 + 4 – 1 = 11<\/p>\n Thus, II alone is sufficient.<\/strong><\/p>\n Instructions<\/b><\/p>\n Each of the questions below consists of a question and two statements numbered I and II given below it.
