Answer: C) 50 Explanation: Let the required number be 'p' 36 of what number is 18 implies 36% of p = 18 => 36 x p/100 = 18 => p = 1800/36 => p = 50.   Hence, 36% of 50 is 18.

Answer: C) 3 Explanation: Given   1.21x0.91.1x0.11   = 1.21x100x0.9x101.1x10x0.11x100   = 9   = 3.

Answer: B) 36 sec Explanation: Time taken to meet the first time = length of track/relative speed   Given the length of the track is 600 m   The relative speed = 25 + 35 = 60 kmph = 60 x 5/18 m   Therefore Time = 60025+35518= 600/60 x (18/5) = 36 sec.

Answer: D) 156 Explanation: Here the given series 7  18  42  94  204 follows a pattern that,  7 7 ×2+4 = 18 18 ×2+6 = 42 42 ×2+10 = 94 94 ×2+16 = 204 Similarly, 4 4 ×2+4 = 12 12 ×2+6 = 30 30 ×2+10 = 70 70 ×2+16 = 156 Hence, the value of P = 156.

Answer: C) 132 Explanation: Given series is    12        16         32          68         ?   Here it follows a pattern that,   12   12 + (2x2) = 16   16 + (4x4) = 32   32 + (6x6) = 68   68 + (8x8) = 132

Answer: D) 700 Explanation: Let number of boys = B Number of girls = G From the given data, 1B/3 + 1G/2 = 300 But given B/3 = 100 => B = 300 G/2 = 300 - 100 G = 200 x 2 => G = 400 Therefore, total number of students in the college = B + G = 700.

Answer: B) 24 Explanation: Sum of Interior angle is 180 .and it is given that interior angle is 150 more than exterior,so let exterior angle is x then interior will be x+150 now , interior + exterior =180x+150+x=180x=15 now , number of sides of polygon = 360 / exterior anglen = 360 / 15n = 24

Answer: C) 3 Explanation: Number = quotient x divisor + remainder;so, herenumber = 138 k + 26=> (23 x 6k) + (23+3)=> 23(6k+1)+3so, remainder is 3.
