A boat takes 38 hours for travelling downstream from point A to point B and coming back to point C midway between A and B. If the velocity of the stream is 4 kmph and the speed of the boat in still water is 14 kmph, what is the distance between A and B? | [
"240 km",
"120 km",
"180 km",
"360 km"
] | D | Explanation :
velocity of the stream = 4 kmph
Speed of the boat in still water is 14 kmph
Speed downstream = (14+4) = 18 kmph
Speed upstream = (14-4) = 10 kmph
Let the distance between A and B be x km
Time taken to travel downstream from A to B + Time taken to travel upstream from B to C(mid of A and B) = 38 hours

Find the ratio of speed of truck to train if truck covers 550m in 1 minute and train covers 33 km in 45 min. | [
"8",
"3:9",
"3:2",
"3:4"
] | D | Explanation:
Using the formula, speed=distance/time
Speed of truck = 550/60 m/s
Speed of train= 33000/(45*60) m/s
Ratio of speed of truck to train= (550/60 ) / [33000/(45*60)]
=3:4
Hence, the ratio is 3:4
ANSWER: D | AquaRat_train |

Mr. Thomas invested an amount of Rs. 13,900 divided in two different schemes A and B at the simple interest rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in 2 years be Rs. 3508, what was the amount invested in scheme B? | [
"2777",
"6400",
"2888",
"2666"
] | B | Let the sum invested in scheme A be Rs. x and that in scheme B be Rs. (13900 - x). Then,
(x * 14 * 2)/100 + [(13900 - x) * 11 * 2]/100 = 3508
28x - 22x = 350800 - (13900 * 22)
6x = 45000 => x = 7500
So, sum invested in scheme B = (13900 - 7500) = Rs. 6400.

A company has two types of machines, type R and type S. Operating at a constant rate, a machine of type R does a certain job in 40 hrs and a machine of type S does the same job in 20 hours. If the company used the same number of each type of machine to do the job in 4 hours, how many machines of type R were used? | [
"11/3",
"10/3",
"7/3",
"8/3"
] | B | Rate of machine R =1/40
Rate of machine S =1/20
since same no of machines used for R and S to do the same work in 4 hrs
So collective rate needed to finish the work in 4 hrs= 1/4
Let the no of machine be x
So, x/40 +x/20 =1/4
3x/40=1/4
x=10/3
So no of machine R is 10/3

A jogger running at 9 km/hr along side a railway track is 240 m ahead of the engine of a 120 m long train running at 45 km/hr in the same direction. In how much time will the train pass the jogger? | [
"25",
"37",
"36",

A man can row downstream at 26 kmph and upstream at 22 kmph. Find the speed of the man in still water and the speed of stream respectively? | [
"24, 2",
"14, 4",

Let the speed of the man in still water and speed of stream be x kmph and y kmph respectively.
Given x + y = 26 --- (1)
and x - y = 22 --- (2)
From (1) & (2) 2x = 48 => x = 24, y = 2.

A number of the form 213ab, where a and b are digits, has a reminder less than 10 when divided by 100. The sum of all the digits in the above number is equal to 13. Find the digit b. | [
"12",
"9",
"7",
"13"
] | C | 213ab may be written as
213ab = 21300 + 10a + b
When 213ab is divide by 100, the reminder is 10a + b. The only way for the remainder to be less that 10 is that a = 0. Hence the sum of the digits is
2 + 1 + 3 + 0 + b = 13
Solve for b
b = 7
