Answer: C) 155 Explanation: Let the number of failed students be x => Number of passed students = 4x  So total number of students was 5x From the given data, If total number of students be 5x – 35 => 4x-35-9/x+9 = 2/1 => 4x – 44 = 2(x + 9) => 4x – 2x = 18 + 44 => x = 31 Total number = 31×5 = 155

Answer: A) 192 Explanation: Given    6   3   3   6   24   ?   Here   6   6 x 0.5 = 3   3 x 1 = 3    3 x 2 = 6   6 x 4 = 24    24 x 8 = 192   The next number in the given series is 192.

Answer: A) 39 Explanation:

Answer: B) Rs.46400 Explanation: Interest received by L from K = 8% of half of Rs.40,000   ⇒8100×20000=1600     Amount received by L per annum for being a working partner = 1200 x 12 = Rs.14,400   Let 'A' be the part of remaing profit that 'L' receives as his share.    Total income of 'K' = only his share from the reamaing profit                                 = 'A', as both share equally.   Given income of L = Twice the income of K   --> (1600 + 14400 + A ) = 2A --> A= Rs.16000 Thus total profit = 2A + Rs.14,400= 2(16000) + 14400                                                    = 32000 +14400 = Rs.46,400.

Answer: B) 2/3 Explanation: Total coins 30 In that, 1 rupee coins 20 50 paise coins 10Probability of total 1 rupee coins =  20C11 Probability that 11 coins are picked = 30C11 Required probability of a coin now picked from the box is 1 rupee = 20C11/30C11 = 2/3.

Answer: D) 70 Explanation: Here the given series is 1, 3, 6, 11, 20, 37, ??, and the logic behind the series is 1 x 2 + 1 = 3 3 x 2 + 0 = 6 6 x 2 + (-1) = 11 11 x 2 + (-2) = 20 20 x 2 + (-3) = 37 37 x 2 + (-4) = 70   Hence, the next number in the given series is 70.
