aquarat_35246 | aquarat | A train overtakes two persons walking along a railway track. The first one walks at 4.5 km/h. The other one walks at 5.4 km/h. The train needs 8.4 and 8.5 seconds respectively to overtake them. What is the speed of the train if both the persons are walking in the same direction as the train? | [
"A)66 km/h",
"B)72 km/h",
"C)78 km/h",
"D)81 km/h"
] | D | 4.5 km/h = (4.5 × 5⁄18) m/sec = 1.25 m/sec.
& 5.4 km/h = (5.4 × 5⁄18) m/sec = 1.5 m/sec.
Let the speed of the train be S m/sec.
Then, (S – 1.25) × 8.4 = (S – 1.5) × 8.5
⇒ 8.4S – 10.5 = 8.5S – 12.75 ⇒ 0.1S = 2.25 ⇒ S = 22.5.
∴ Speed of the train = (22.5 × 18⁄5) km/h = 81 km/h

] | B | a/b + b/a = (a2]/ab
a + b = + b2)/ab = (a2 + b2 + a + b)/ab

"A)4 minutes",
"B)2/7 minutes",
"C)32/7 minutes",
"D)224/7 minutes"
] | C | Pipe A can fill a tank in 32 minutes --> the rate of A = 1/32 tank/minute;
Pipe B can fill the same tank5 times fasterthan pipe A --> the rate of B = 1/32 + 5/32 = 6/32 tank/minute.
Their combined rate = 1/32 + 6/32 = 7/32 tank/minute;
Therefore, A and B can fill the tank in 32/7 minutes.
