If a person walks at 12 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance traveled by him is:
[ "50 km", "80 km", "60 km", "100 km" ]

Two trains of length 150 m and 250 m are 100 m apart. They start moving towards each other on parallel tracks, at speeds 18 kmph and 36 kmph. In how much time will the trains cross each other?
[ "87/7 sec", "80/5 sec", "20/7 sec", "100/3 sec" ]
D
Relative speed = (18 + 36)* 5/18 = 3 * 5 = 15 mps. The time required = d/s = (100 + 150 + 250)/15 = 500/15 = 100/3 sec. Answer: C

The average price of 10 oranges is Rs. 12 while the average price of 8 of these oranges is Rs. 11.75. Of the remaining two oranges, if the price of one orange is 30% more than the price of the other, what is the price of each of these two oranges?
[ "Rs 10, Rs 16", "Rs 12, Rs 14", "Rs 5, Rs 7.50", "Rs 11.1, Rs 14.9" ]

Two trains of equal lengths take 10 sec and 15 sec respectively to cross a telegraph post. If the length of each train be 120 m, in what time will they cross other travelling in opposite direction?
[ "12 sec", "55 sec", "43 sec", "99 sec" ]
A
Speed of the first train = 120/10 = 12 m/sec. Speed of the second train = 120/5 = 8 m/sec. Relative speed = 12 + 8 = 20 m/sec. Required time = (120 + 120)/20 = 12 sec. Answer: B
