Option(b) Explanation: x = 13p + 11 and x = 17q + 9 13p + 11 = 17q + 9 17q - 13p = 2 2 + 13푝 q= 17 2 + 13푝 The least value of p for which q= a whole number is p = 26 17 x = (13 x 26 + 11) = (338 + 11) = 349 52. Option(b) Explanation: Let 7589 -x = 3434 Then, x = 7589 - 3434 = 4155 53. Option(a) Explanation: Unit digit in the given product = Unit digit in (4 x 8 x 7 x 3) = (672) = 2 54. Option(c) Explanation: 90 = 10 x 9 Clearly, 653xy is divisible by 10, so y = 0 Now, 653x0 is divisible by 9. So, (6 + 5 + 3 + x + 0) = (14 + x) is divisible by 9. So, x = 4. Hence, (x + y) = (4 + 0) = 4. 55. Option(b) Explanation: 3897 x 999 = 3897 x (1000 - 1) = 3897 x 1000 - 3897 x 1 = 3897000 - 3897 = 3893103. 56. Option(d) Explanation: The square of a natural number nerver ends in 2. 143642 is not the square of natural number. 57. Option(a) Explanation: Number is divisible by 9, if sum of all digits is divisible by 9, so (2+2+3+*+4+3+1) = 15+* should be divisible by 9, 15+3 will be divisible by 9, So that least number is 3. 58. Option(c) Explanation: 2/3 = .66, 3/4 = .75, 4/5 = .8 and 5/6 = .833 So biggest is 5/6 and smallest is 2/3 Their difference is 5/6 - 2/3 = 1/6 59. Option(c) Explanation: = √248 + √64 = √256 =16 60. Option(d) Explanation: L.C.M. of 21, 36, 66 = 2772 Now, 2772 = 2 x 2 x 3 x 3 x 7 x 11 To make it a perfect square, it must be multiplied by 7 x 11. So, required number = 2 x 2 x 3 x 3 x 7 x 7 x 11 x 11 = 213444 61. Option(b) Explanation: = √81 +√0.81 = 10.09−X = 9+0.9=10.09−X = X=10.09−9.9=0.19 62. Option(b) Explanation: 10+15+20+25+30 100 Average= = =20 5 5 63. Option(d) Explanation: As number of girls and boys is not given so result cant be computed 64. Option(d) Explanation: Let the average after 17th match is x Then the average before 17th match is x-3 So 16(x-3) + 87 = 17x => x = 87 - 48 = 39 65. Option(c) Explanation: Total weight increased is 1.5 * 10 = 15. So weight of new person is 45+15 = 60 66. Option(c) Explanation: Let the new S.P. be x, then. (100 - loss%):( 1st S.P.) = (100 + gain %):( 2nd S.P.) 95 105 = ( = ) 1140 푥 = 1260 67. Option(c) Explanation: Let the S.P = 100 Then C.P. = 25 Profit = 75 Profit% = 75/25 * 100 = 3005 68. Option(b) Explanation: Let the Cost Price of 1 item = Re. 1 Cost Price of 16 items = 16 Selling Price of 16 items = 12 Loss = 16 - 12 = Rs 4 Loss % = (4/16)* 100 = 25% 69. Option(c) Explanation: Treat 2:9 as 2/9 and x:18 as x/18, So we get 2/9 = x/18 => 9x = 36 => x = 4 70. Option(b) Explanation: Let C = x. Then A = (x—20) and B = (x—40). x + x - 20 + x - 40 = 120 Or x=60. A: B: C = 40:20:60 = 2:1:3. B's share = Rs. 120*(1/6) = Rs. 20 71. Option(c) Explanation: Let the third number be x. First Number (120/100)*x = 6x/5 Second Number (150/100)*x = 3x/2 Ratio = 6x/5:3x/2 => 4:5 72. Option(b) Explanation: Firstly we will find 1 day work of both A and B, then by adding we can get collective days for them, So, A's 1 day work = 1/10 B's 1 day work = 1/15 1 1 (A+B)'s 1 day work =( + ) 10 15 3+2 = ( ) 30 1 = 16 73. Option(b) Explanation: We are having time and speed given, so first we will calculate the distance. Then we can get new speed for given time and distance. Time = 50/60 hr = 5/6 hr Speed = 48 mph Distance = S*T = 48 * 5/6 = 40 km New time will be 40 minutes so, Time = 40/60 hr = 2/3 hr Now we know, Speed = Distance/Time New speed = 40*3/2 kmph = 60kmph 74. Option(a) 75. Option(d) General Awareness: 76. Option(c) 77. Option(a) 78. Option(a) 79. Option(c) 80. Option(b) Explanation: The parliament of India has power to make laws, organizing jurisdiction and powers of Supreme Court.
