Two trains of length 100 m and 280 m are running towards each other on parallel lines at 42 kmph and 30 kmph respectively. In what time will they be clear of each other from the moment they meet? | [
"82 sec",
"19 sec",
"10 sec",

And,
= [{2 *(X +10)} /2] - 2
According to question,
[{2 *(X +10)} /2] - 2 = half of 88

X + 10 = 46
X + 10 = 46
X = 46 - 10

Mr.Jones gave 40% of the money he had to his wife. He also gave 20% of the remaining amount to his 3 sons. and half of the amount now left was spent on miscellaneous items and the remaining amount of Rs.12000 was deposited in the bank. How much money did Mr.jones have initially? | [
"62000",
"40000",
"50000",
"45000"
] | C | Explanation :
Let the initial amount be x,
Amount given to his wife =(40/100)x=2x/5
Balance = (x-(2x/5)) = 3x/5
Amount given to his wife = (20/100)*(3x/5) = 3x/25
Balance = 3x/5-3x/25 = 12x/25
Amountt spent on miscellaneous items = (1/2)*(12x/25) = 6x/25 which is equal to 12000
Hence,
=> 6x/25 = 12000
=> x = 50000

In an election between two candidates, one got 55% of the total valid votes, 20% of the votes were invalid. If the total number of votes was 7000, the number of valid votes that the other candidate got, was: | [
"2800",
"2520",
"2900",
"2700"
] | B | E
Number of valid votes = 80% of 7000 = 5600.
Valid votes polled by other candidate = 45% of 6000
= (45/100 x 5600) = 2520. | AquaRat_train |
8 is 4% of a, and 4 is 8% of b. c equals b/a. What is the value of c? | [
"5",
"4",
"1/4",
"1/32"
] | C | Explanation :
Given,
=>4a/100=8.
=>a=8×(100/4)=200. ---------(i)
And,
=>(8/100)×b=4.
=>b=50. ---------(ii)
Now, c=b/a ( from (i) and (ii) )
=>50/200.
=>1/4.

A four-character password consists of one letter of the alphabet and three different digits between 1 and 9, inclusive. The letter must appear as the second or third character of the password. How many different passwords are possible? | [
"5,040",
"26,208",
"52,000",
"18,720"
] | B | 4 character password: DLDD
First digit can be chosen in 9 ways.
The letter can be chosen in 26 ways.
Next digit can be chosen in 8 ways.
Next digit can be chosen in 7 ways.
This gives us 9*26*8*7ways
Now, the letter can also be DDLD so there will be another 9*26*8*7 ways
Total = 9*26*8*7*2 = 26,208 ways C | AquaRat_train |

On dividing a number by 357, we get 38 as remainder. On dividing the same number 17, what will be the remainder ? | [
"0",
"4",
"3",
"11"
] | B | Let x be the number and y be the quotient. Then,
x = 357 x y + 38
= (17 x 21 x y) + (17 x 2) + 4
= 17 x (21y + 2) + 4)
Required remainder = 4.

A train 100m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is: | [
"36",
"41",

=10m/sec.
=10x18/5km/hr
= 36 km/hr.
Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr.
x - 5 = 36 =41km/hr.
