प्र: A laborer is engaged for 30 days on the condition that he receives Rs.25 for each day he works and is fined Rs.7.50 for each day is absent. He gets Rs.425 in all. For how many days was he absent ? 1343 0

उत्तर : 1. "10 days"
व्याख्या :
Answer: A) 10 days Explanation: For 30 days he receives 30 x 25 = 750 Actually he gets 425 Therefore, Fine is 750 - 425 = 325 => No of days absent = 325/(25+7.50)= 10

प्र: A sum of money becomes 7/6 of itself in 3 years at a certain rate of simple interest. The rate per annum is ? 1862 0

उत्तर : 2. "50/9 %"
व्याख्या :
Answer: B) 50/9 % Explanation: Let sum = S. Then, amount = 7S/6 S.I. = 7S/6 - S = S/6; Time = 3 years. Rate = (100 x S) / (S x 6 x 3) = 5 5/9 = 50/9 %.

प्र: On multiplying a number by 7, the product is a number each of whose digits is 3. The smallest such number is ? 1264 0

उत्तर : 3. "47619"
व्याख्या :
Answer: C) 47619 Explanation: By hit and trail, we find that 47619 x 7 = 333333. 7) 333333 (47619 333333---------------- 0 And 476190476 x 7 = 3333333333 but smallest number is 47619.

प्र: Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is ? 1207 0

उत्तर : 4. "3 : 2"
व्याख्या :
Answer: D) 3 : 2 Explanation: Let the speeds of the two trains be x m/sec and y m/sec respectively. Then, length of the first train = 27 x meters, and length of the second train = 17 y meters. (27 x + 17 y) / (x + y) = 23 => 27 x + 17 y = 23 x + 23 y => 4 x = 6 y => x/y = 3/2.

प्र: P is faster than Q. P and Q each walk 24 km. The sum of their speeds is 7 km/hr and the sum of times taken by them is 14 hours. Then, P's speed is equal to ? 3998 0

उत्तर : 2. "4 km/hr"
व्याख्या :
Answer: B) 4 km/hr Explanation: Let P's speed = x km/hr. Then, Q's speed = (7 - x) km/ hr. So, 24/x + 24/(7 - x) = 14 x2 - 98x + 168 = 0 (x - 3)(x - 4) = 0 => x = 3 or 4. Since, P is faster than Q, so P's speed = 4 km/hr and Q's speed = 3 km/hr.

प्र: A is 30% more efficient than B. How much time will they, working together, take to complete a job which A alone could have done in 23 days ? 1502 0

उत्तर : 3. "13 days"
व्याख्या :
Answer: C) 13 days Explanation: Ratio of times taken by A and B = 100 : 130 = 10 : 13.Suppose B takes x days to do the work. Then, 10 : 13 :: 23 : x => x = ( 23 x 13/10 ) => x = 299 /10. A's 1 day's work = 1/23 ;B's 1 day's work = 10/299 . (A + B)'s 1 day's work = ( 1/23 + 10/299 ) = 23/299 = 113 . Therefore, A and B together can complete the work in 13 days.

प्र: When 0.46 is written in simplest form, the sum of the numerator and the denominator is ? 1831 0

उत्तर : 2. "73"
व्याख्या :
Answer: B) 73 Explanation: 0.46 = 46/100 = 23/50. Sum of the numerator and denominator is 23 + 50 = 73

प्र: The second day of a month is Sunday, What will be the last day of the next month which has 31 days ? 6604 0

उत्तर : 4. "Can't be determined"
