In a mens hostel, there were 95 students. To accommodate 30 more students the average is decreased by rupees 5. But total expenditure increased by Rs.500. Find the total expenditure of the hostel now ?
[ "Rs.4680", "Rs.4287", "Rs.4101", "Rs.4129" ]
A
Explanation: Let the expenditure on the 95 students be 'x' Then, 95x + 500 = 120(x – 5) 95x + 500 = 120x - 600 120x - 95x = 1100 25x = 1100 => x = 44 Therefore, total expenditure of the hostel becomes 95 x 44 + 500 = 4680. Answer: A

Two trains, each 100 m long, moving in opposite directions, cross other in 8 sec. If one is moving twice as fast the other, then the speed of the faster train is?
[ "16 km/hr", "17 km/hr", "15 km/hr", "60 km/hr" ]
D
Let the speed of the slower train be x m/sec. Then, speed of the train = 2x m/sec. Relative speed = ( x + 2x) = 3x m/sec. (100 + 100)/8 = 3x => x = 25/3. So, speed of the faster train = 50/3 = 50/3 * 18/5 = 60 km/hr. Answer: C
