37). If A is coded as C, M as I, N as P, S as O, I as A, P as N, E as M, O as E and C as S, then the code of COMPANIES will be                                                                                                                   (1) SPEINMOAC   (2) NCPSEIOMA


(3) SMOPIEACN  (4) SEINCPAMO                                         [C—S, O—E,M—I,P—N,A—C,N—P,I—A,E—M,S—O,Thus COMPANIES becomes SEINCPAMO,Answer is (4)]                                                                                                    


38). Among the following, identify the continuous type of data :                                                                    


(1) Number of languages a person speaks (2) Number of children in a household (3) Population of cities (4) Weight of students in a class                                                          


[There are two types of data namely continuous or discrete. Discrete data is counted, continuous data is measured. Discrete data have finite values Continuous data technically have an infinite number of steps, which form a continuum.  Number of children in a household, Number of languages a person speaks, The number of questions correct all are discrete—they are finite and countable numbers.. Height of children, Speed of the trainetc are examples of Continuous data,The answer is(4)]


39). Ali buys a glass, a pencil box and a cup and pays ‘ 21 to the shopkeeper. Rakesh buys a cup, two pencil boxes and a glass and pays ‘ 28 to the shopkeeper. Preeti buys two glasses, a cup and two pencil boxes and pays ‘ 35 to the shopkeeper. The cost of 10 cups will be                                                                                            (1) ‘ 40      (2) ‘ 60   (3) ‘ 80        (4) ‘ 70                                                                                                                            


[ Let the cost of a glass be x,a pencil box be yand a cup be z.                                    x+y+z=21(1)             ,x+2y+z=28 (2)                2x+2y+z=35 (3)                                                         


Solving equations2 and1,we get y=7                                                                                 Solving equations2 and3,we get x=7                                                                                         Substituting  x and y we get z =7,cost of 10 cups is70 answer(4)]


40). Out of four cities given below three are alike in some manner while the fourth one is different. Identify the odd one                                                                                                    (1) Lucknow  (2) Rishikesh   (3) Allahabad       (4) Patna    [(1) Lucknow is far from Ganges]                                                                                                                                                    


41). Given below are some characteristics of reasoning. Select the code that states a characteristic which is not of deductive reasoning :

(2) The conclusion should be supported by the premise/premises.                                                     


(3) The conclusion must follow from the premise/premises necessarily.                                              


(4) The argument may be valid or invalid.                                                                                           [Two types of reasoning namely inductive and deductive.IPG means Inductive is from particular to general.Inductive reasoning is based upon  observation and experiment .Hence answer (1) ]                                                                                                                                               


42). The missing term in the series 1, 4, 27, 16, ?, 36, 343, … is  (1) 30    (2) 49    (3) 125      (4) 81                                                               


[ In the series 1,  4,  27,  16,  ?,  36,  343, …                                                                              we have  1cube,2square,3cube,4 square 5cube,6square,7cube.......                                 The missing term is5cube=125answer is  (3)]                                                                         


43)The next term in the following series YEB, WFD, UHG, SKI, ? will be                                              (1) TLO      (2) QOL          (3) QLO              (4) GQP                                                        


[The series is YEB, WFD, UHG, SKI,—— First termYcrosses one letter fach to backW.U.S and reachesQ,first letter of the missing part. Second letterE jumps toF,H,Kand reachesO.The answer is (2) QOL]                                                                                                                                          


44). Among the following propositions two are related in such a way that they cannot both be true but can both be false. Select the code that states those two propositions.
