Answer: A) Rs. 1100 Explanation: Let the sum be Rs.x. Then,     x1+101002-x=1155   ⇒x11102-1=1155   => x =5500   sum = Rs. 5500.   So, S.I = Rs. 5500×5×4100 = 1100

Answer: A) 1/26 Explanation: Here in this pack of cards, n(S) = 52 Let E = event of getting a queen of the club or a king of the heart Then, n(E) = 2 P(E) = n(E)/n(S) = 2/52 = 1/26

Answer: C) 7/8 & 3/8 Explanation: Given 0.875 and 0.375 0.875 :: After decimal point there are 3 digits 875 Now, mutiply and divide 0.875 with 1000 0.875 x 10001000 = 8751000 Now, this can be reduced to fraction 78Therefore, 0.875 as fraction = 78 Similarly, 0.375 ::  After decimal point there are 3 digits 375 Now, mutiply and divide 0.375 with 1000 0.375 x 10001000 = 3751000Now, this can be reduced to fraction 38Therefore, 0.375 as fraction = 38

Answer: A) 225 deg Explanation: Angle of triangle = 180 × 3/12 = 45 deg Other angles of the triangle are = 60 deg, 75 deg Angle of quadrilateral = 360 - (45 + 60 + 75) = 180 deg Therefore, the four angles of the quadrilateral are 45, 60, 75 & 180 degrees. Hence, the sum of largest and smallest angle of the quadrilateral are 180 + 45 = 225 deg.

Answer: B) 13 days Explanation: Ratio of times taken by P & Q = 100 : 130 = 10:13   Let Q takes x days to do the work Then, 10:13 :: 23:x => x = 23x13/10 => x = 299/10   P's 1 day's work = 1/23 Q's 1 day's work = 10/299 (P+Q)'s 1 day's work = (1/23 + 10/299) = 23/299 = 1/13 Hence, P & Q together can complete the work in 13 days.

Answer: C) 21, 15, 23 Explanation: Given number series is 9 17 11 19 13  Here the pattern is 9 9 + 8 = 17 17 - 6 = 11 11 + 8 = 19 19 - 6 = 13 13 + 8 = 21 21 - 6 = 15 15 + 8 = 23

Answer: B) 12 Explanation: x128 = 162x   Then x2 = 162x128       = Sqrt of 82 x 62 x 32      = 8 x 6 x 3      x2  = 144.    x  = 12.

Answer: C) 6 Explanation:   It is in the form of a2-b2a-b = a+ba-ba-b = a+b   Here a = 3.39   b = 2.61     = 3.39 + 2.61 = 6.
