A train 400 m long can cross an electric pole in 40 sec and then find the speed of the train? | [
"38 Kmph",
"36 Kmph",
"42 Kmph",
"40 Kmph"
] | B | Length = Speed * time
Speed = L/T

In a City, 35% of the population is composed of migrants, 20% of whom are from rural areas. Of the local population, 48% is female while this figure for rural and urban migrants is 30% and 40% respectively. If the total population of the city is 728400, what is its female population ? | [
"277880",
"324138",
"379010",
"378908"
] | B | Explanation:
Total Population = 728400
Migrants = 35 % of 728400 = 254940
local population = (728400 - 254940) = 473460.
Rural migrants = 20% of 254940 = 50988
Urban migrants = (254940 - 50988) = 203952
Female population = 48% of 473460 + 30% of 50988 + 40% of 203952 = 324138

A train overtakes two persons who are walking in the same direction in which the train is going, at the rate of 2 kmph and 4 kmph and passes them completely in 9 and 10 seconds respectively.The length of the train is: | [
"55M",
"40M",
"50M",
"45M"
] | C | 2 kmph = ( 2 x 5/18) m/sec = 5/9 m/sec.
4 kmph = ( 4 x 5/18)m/sec = 10/9 m/sec.
Let the length of the train be x metres and its speed by y m/sec.
Then, ( x / y-5) = 9 and x / (y-10/ 9) = 10.
Therefore 9y - 5 = x and 10(9y - 10) = 9x
=9y - x = 5 and 90y - 9x = 100.
On solving, we get: x = 50 ANSWER : D | AquaRat_train |
A certain basketball team that has played 2/3 of its games has a record of 15 wins and 5 losses. What is the greatest number of the remaining games that the team can lose and still win at least 3/4 of all of its games? | [
"6",
"4",
"2",
"7"
] | C | 15 wins, 3 losses - total 20 games played.
The team has played 2/3rd of all games so total number of games = 30
3/4th of 30 is 22.5 so the team must win 23 games and can afford to lose at most 7 total games. It has already lost 5 games so it can lose another 2 at most.

"13:5",
"13:3",
