Question 1 A train starts from station P towards Q with certain speed. Due to a problem, after crossing 50km, the train slows down to 2/3 rd of its actual speed and it reaches Q 50 minutes later than the planned time. Suppose the technical problem had happened after crossing 60 km and the train would had reached 40 minutes late. What is the actual(original) speed of the train and what is the distance between P and Q ? a)30km/hr, 100km b)20km/hr,80km c)40km/hr,150km d)50km/hr,150km Answer : a)30km/hr, 100km Solution: Let the distance between P and Q be X and the speed initially be V. Note that the train travels 50km with speed V and the remaining distance(X-50)km with speed 2/3 of V. According to the above condition, with the formula " distance/speed = time", we can have Time Taken For First 50 Km + Time Taken For Remaining (X-50) Km = Planned Time + Extra Time Due To Problem [50/V]+[(X-50)/(2V/3)] = [X/V]+5/6 (here 50 minutes = 5/6 hours) [100+3X-1...

Question 1 If 11 + 21 = 3, 34 + 45 = 32 and 42 + 53 = 23 then 64 + 75 = ? a)59 b)43 c)69 d)53 Answer : a)59 Solution : Let AB be the first number of the addition and CD be the second one. By closely observing, we can conclude that questions are in the general form AB + CD = (A x B) + (C x D). i.e.,11 + 21 = 1 x 1 + 2 x 1 = 1 + 2 = 3 34 + 45 = 3 x 4 + 4 x 5 = 12 + 20 = 32 42 + 53 = 4 x 2 + 5 x 3 = 8 + 15 = 23. Therefore, the result for 64 + 75 = 6 x 4 + 7 x 5 =24 + 35 = 59. Question 2 If 15 + 22 = 32, 19 + 35 = 62 and 23 + 49 = 101 then 34 + 52 = ? a)91 b)101 c)172 d)72 Answer : c)172 Solution: By observing the question we can generalize the equations to, AB + CD = (AB x C) + D Then, 15 + 22 = (15 x 2)+ 2 = 30 + 2 = 32 19 + 35 = (19 x 3)+ 5 = 57 + 5 = 62 23 + 49 = (23 x 4)+ 9 = 92 + 9 = 101 Similarly,34 + 52 = (34 x 5)+ 2 = 170 + 2 = 172 Hence 172 is the required answer. Question 3 If 3 + 5 = 19, 5 + 9 = 61 and 9 + 12 = 117 then 13 + 14 = ? a)1...

Question 1 A manufacturer reduces the size of his machine of Material1 from 30" to 28" and that of Material2 from 24" to 23". He normally spends Rs.1440 for Material1 and Material2. 3/4th of the amount spent would be for Material1. How much will he save under the size of new size (Assuming that the costs incurred by the machines are directly proportional to their sizes)? a)Rs.85 b)Rs.87 c)Rs.86 d)Rs.88 Answer : b)Rs.87 Solution: The manufacturer totally spends Rs.1440 for both material 1 and 2. Out of this 3/4th is entirely for Material1. Amount spent on Material1 = 1440 x 3/4 = Rs.1080 i.e, he spent Rs.1080 for Material1 of 30" and he reduces 2". Size Amount 30" Rs.1080 2" ? Amount saved on Material1 = 1080 x 2/30 = Rs.72 Amount spent on Material2 = total amount - amount for Material1 = 1440 - 1080 = Rs.360. i.e., he spent Rs.360 for Material2 of 24" and he reduces 1". Size Amount 24" Rs.360 ...
