Logical Reasoning Questions1.Three letter groups from the following four-letter groups are similar in some way and one is unequal. Select the odd alphabets.​​ A. TWUV​​ B. HNLJ​​ C. MSOQ​​ D. DGEF2.In a code language, TEMPLE is written as DKOLDS. In the same code language, how will be WORSHIP written as -----?​​ A. OHGRQNV​​ B. OGHQRVN​​ C. QJITSPX​​ D. VNQGHOR3.Select the set in which the numbers are interlinked in the same way as the numbers are related in the set given below.​​ (7, 13, 21)​​ A. (12, 18, 25)​​ B. (17, 22, 30)​​ C. (9, 16, 25)​​ D. (2, 8, 16)4.Three words out of the following four words are somehow similar and one word is uneven. Choose the odd word.​​ A. Tendency​​ B. Endurance​​ C. Stability​​ D. Persistence5. select the word pair whose two words are related to each other in the same way as the words of the word pair below are related.​​ Heat: Sun​​ A. House: Terrace​​ B. Vitamin: Fruit​​ C. Environment: Humidity​​ D. Ride: car6.If CAB is coded as 6 and BED is coded as 40, then how will HAD be coded as?​​ A. 16​​ B. 52​​ C. 32​​ D. 467.Three of the following four letter​​ clusters are alike in a certain way and one different. Pick the odd one out.​​ A. RQST​​ B. FGHJ​​ C. MLNO​​ D. CBDE8.​​ .Select the set in which the number are related in the same way as are the numbers of the following set.​​ (5,13,12)​​ A. (13,17,11)​​ B. (11,15,9)​​ C. (15,19,13)​​ D. (6,10,8)9. Select the option that is related to the third letter-cluster in the same way as the second letter-cluster is related to the first letter-cluster.​​ MNOP : LONQ :: FGHI : ?​​ A. GFIJ​​ B. EGHJ​​ C. DHGK​​ D. EHGJ10.Find the missing number (?)​​ 6, 9, 15,24, ?, 51​​ A.29​​ B. 31​​ C. 35​​ D.36               Answer key 1 - B Solution: All except HNLJ has one vowel. So the odd letter group is option (B)2 -A Solution: First, the letter of word written in reverse order and then each alphabet moves 1 step backward I.e. ELPMET- DKOLDA ​​ Similarly, PIHSROW- OHGRQNV3-​​ D Solution:7+6=13, 13+8=21 Similarly, 2+6=8, 8+8=164-​​ A Solution : endurance, stability and persistence means the state of being stable. And Tendency relates to the ability of a person to do something. Hence, the odd word is (a) tendency.​​ 5-​​ B Solution: Sun is the source of heat. Likewise, fruit is the source of vitamin. Therefore, the correct option is(B)6-​​ C Solution: C = 3, A = 1, B =2 The code is given by the multiplication of these place values. CAB = 3 x 1 x 2 = 6 Similarly, BED= 2 x 5 x 4 = 40 Therefore, HAD = 8 x 1 x 4 = 327-​​ B Solution: Except FGHJ, all other options are having first two letters in​​ reverse order. Hence, option (B) is different from the rest.8-​​ D Solution: The sum of all the numbers in the given number set is even 5 + 13 + 12 =30  ​​ ​​ ​​ ​​ ​​ ​​ ​​ ​​ ​​​​ So, the given options 13 + 17 + 11 = 41 (odd),11 + 15 + 9 = 35 (odd), 15 + 19 + 13 = 47 (odd), 6 + 10 + 8 = 24 (even)9-D Solution: M-1=L,N+1=O,O-1=N,P+1=Q ​​ Similarly, F-1=E,G+1=H, H-1=G, I+1=J option (D) EHGJ10-D Solution: Series is increasing by 3, 6, 9, 15, 18(multiple of 3)​​ (function( $ ) { //footnotes $('.defaultNote').children(":first").css('cursor', 'pointer'); $('.defaultNote').children(":first").click(function(){ var gotoID = '#' + $(this).parent().attr('id'); $('html, body').animate( { scrollTop: $('a[href="' + gotoID + '"]').offset().top - 60, }, 250, 'linear' ) }); }(jQuery)); var numFormat = ",."; (function( $ ) { "use strict"; //do some cleaning on load var sortCells = $('td[data-sorting], th[data-sorting]'); sortCells.each(function(){ var first = $(this).text().trim().charAt(0); if (first == '@'){ var oldHTML = $(this).html(); var newHTML = oldHTML.replace('@', ''); $(this).html(newHTML); } }); function sortingTable(node, pos, ordBy){ var rows = node.children('tbody').children('tr').get(); rows.sort(function(a, b) { var X = $(a).children('td').eq(pos).text().toUpperCase(); var Y = $(b).children('td').eq(pos).text().toUpperCase(); if (numFormat != '.,'){ //we are dealing with a different locale and we need to do some //transformation in numbers X = convert2number(X); Y = convert2number(Y); } else { X = X.replace(/,/g, '').replace(/ /g, ''); Y = Y.replace(/,/g, '').replace(/ /g, ''); } var currencies = ['$', '¥', '£', '€']; var arrayLength = currencies.length; var XX = X; var YY = Y; for (var i = 0; i < arrayLength; i++) { XX = XX.replace(currencies[i], ''); YY = YY.replace(currencies[i], ''); } if (!isNaN(XX) && !isNaN(YY)){ var floatXX = parseFloat(XX); var floatYY = parseFloat(YY); return -(floatYY-floatXX) * ordBy; } else if (!isNaN(XX) && isNaN(YY)){ return -1 * ordBy; } else if (isNaN(XX) && !isNaN(YY)){ return ordBy; } else { if(X < Y) { return -1 * ordBy; } if(X > Y) { return 1 * ordBy; } return 0; } }); $.each(rows, function(index, row) { node.children('tbody').append(row); }); } function removeTableCellDecoration() { $("td[data-sorting], th[data-sorting]").removeClass('sortDecorator'); } //unbind the click event just in case we are loading more than one document $("td[data-sorting], th[data-sorting]").off('click'); $("td[data-sorting], th[data-sorting]").click(function(){ removeTableCellDecoration(); $(this).addClass('sortDecorator'); //get desired ordering var ordering = $(this).attr('data-sortOrdering'); if (ordering == 'ASC'){ var ordBy = -1; $(this).attr('data-sortOrdering', 'DESC'); } else { var ordBy = 1; $(this).attr('data-sortOrdering', 'ASC'); } var cellPosition = $(this).prevAll().length; var table = $(this).parents('table:first'); sortingTable(table, cellPosition, ordBy); }); function convert2number(str) { str = str.trim(); if (str.match(/^\d+/)) { //we have to take special care when the thousand separators are '.' var result_0 = str.replace(/\./g, '_@_'); var result_1 = result_0.replace(window.numFormat[0], '.'); var result = result_1.replace(/_@_/g, ''); result .replace(/ /g, ''); return result; } else { return str; } } }(jQuery));
