A boat covers a distance of 30 km downstream in 2 hours while it takes 6 hours to cover the same distance upstream. What is the speed of the boat in km/hr ?

A. 5

B. 7.5

C. 10

D. 12

Answer : C. 10

Explanation :

  • Speed of boat downstream
    = Distance covered / Time taken
    = 30/2
    = 15 km/h
  • Now, speed of boat upstream
    = Distance covered / Time taken
    = 30/6
    = 5 km/h
  • Now, speed of boat = (Speed downstream + Speed upstream)/2
    = (15 + 5)/2
    = 20/2
    = 10 km/h.

A motorboat whose speed is 15 km/hr in still water goes 30km downstream and comes back in four and a half hours. The speed of the stream is ?

A. 4.5 km/hr

B. 6 km/hr

C. 7 km/hr

D. 5 km/hr

Answer : D. 5 km/hr

Explanation :

Let the speed of the stream be x km/hr. Then,
Speed downstream = (15 + x) km/hr
Speed upstream = (15 – x) km/hr

We know from question that it took 4(1/2)hrs to travel back to same point.
So, (30/15 + x) + (30/15 − x) = 4(1/2)
=> 900/225 − x2 = 9/2
=> 9x2 = 225
=> x = 5km/hr.

Ramakant wants to earn Rs. 1500 interest on his deposits. He plans to buy a sack of grains with the interest. He puts Rs. 5,000 into his account that earns 2.5% interest. How long will he need to leave his money in the account to earn this interest that would help him buy the sack of grains ?

A . 8 years

B . 10 years

C . 12 years

D . 15 years

Answer : C . 12 years

Explanation :

S.I = 1500
P = 5000
R = 2.5
S.I = P * T * R / 100
P * T * R / 100 = 1500
(5000 * 2.5 * T) / 100 = 1500
T = 12 years.

A Certain sum of money amounts to Rs 2500 in a span of 5 years and further to Rs.3000 in a span of 7 years at simple interest. The sum is_____

A. 1200

B. 1250

C. 1050

D. 1000

Answer : B. 1250

Explanation :

As the rate of interest for both the cases are same
A1, A2 = Total Amounts , P = Principal Amount , T1, T2 = Time Period involved in years
(A1 – P) / T1 = (A2 – P) / T2
(2500 – P) / 5 = (3000 – P) / 7
17500 – 7P = 15000 – 5P
P = 1250

Consider the following quotients :
1) 368.39 divided by 17
2) 170.50 divided by 62
3) 875.65 divided by 83
Their correct sequence in decreasing order is :

A. 1, 3, 2

B. 2, 1, 3

C. 2, 3, 1

D. 3, 1, 2

Answer : A. 1, 3, 2

Explanation :

  • 36839/17 = 2167, Dividend contains 2 places of decimal.
    So, 368.39 / 17 = 21.67
  • 17050/62 = 275, Dividend contains 2 places of decimal.
    So, 70.50/62 = 2.75
  • 87565/83 = 1055, Dividend contains 2 places of decimal.
    So, 875.65/83 = 10.55

Since 21.67 > 10.55 > 2.75. The desired order is 1, 3, 2.

The LCM of two positive no’s is 168 and their product is 504. what is the difference in their squares?

A. 175

B. 216

C. 9

D. 135

Answer : D. 135…

504 = 2*2*2*3*3*7 = 8*3*3*7 = 24*21
168 = 2*2*2*3*7
It means 3 will come in both the numbers as 3 is coming once in LCM but coming as 9 in product.
so possible numbers are 24 and 21.

Now the difference of the square of these numbers is a^2-b^2 = (a+b)(a-b)
= (24+21)(24-21)
= 45(3)
= 135

A. 355 mtrs

B. 325 mtrs

C. 365 mtrs

D. 312 mtrs

Answer : A. 355 mtrs

Explanation :

Given speed = 63 km/hr = 63 × 5/18 = 35/2 m/s
Let the length of the bridge = x mts
Given time taken to cover the distance of (170 + x)mts is 30 sec.
We know speed = distance/time
35 / 2 = ( 170 + x ) / 30
x = 355 mts.

A train speed past a pole in 15 seconds and a platform 100 m long in 25 seconds. Its length is ?

A. 50 m

B. 150 m

C. 200 m

D. None of these

Answer : B. 150 m

Explanation :

Let the length of the train be x metres and its speed by y m/sec.
Then, x / y = 15
=> y = x / 15
(x + 100) / 25 = x / 15
=> 15(x + 100) = 25x
=> 15x + 1500 = 25x
=> 1500 = 10x
=> x = 150 m.

Two trains of equal length, running in opposite directions, pass a pole in 18 and 12 seconds. The trains will cross each other in ?

A. 14.4 sec

B. 15.5 sec

C. 18.8 sec

D. 20.2 sec

Answer : A. 14.4 sec

Explanation :

Let length of each train be x meter.
Then, speed of 1st train = x/18 m/sec
Speed of 2nd train = x/12 m/sec

Now, When both trains cross each other, time taken
= [ 2x/((x / 18 ) + (x / 12)) ] = 2x / [(2x + 3x) / 36] = 2x * 36 / 5x
= 72 / 5
= 14.4 seconds.
