RRB Group D Mock Test - 33 - Question 63

Find the speed of the flight if it takes 6 hrs 30 mins to travel 2,210 km ?

Detailed Solution for RRB Group D Mock Test - 33 - Question 63

6 hrs 30 mins = 6.5 hrs

Speed = \frac{distance}{time} = \frac{2210}{6.5} = 340 kmphtimedistance​=6.52210​=340kmph

SO the answer is option D.

RRB Group D Mock Test - 33 - Question 64

Two trains X and Y are travelling in the same direction. Their lengths are 850m and 950m respectively. They took 6 mins to cross each other. Find the speed of train X if the speed of train Y is 90 kmph ?

Detailed Solution for RRB Group D Mock Test - 33 - Question 64

Let the speed of train X is x kmph

Relative speed = 90-x kmph (if train Y is faster than train X)

Speed = distance/time = (850+950)/(6*60) = 1800/360 = 5 m/s = 5*(18/5) = 18 kmph

90 - x = 18 kmph

x = 90 - 18 = 72 kmph

So the answer is option A.

Case 2 :(If train Y is slower than train X)

x - 90 = 18, then x = 90 + 18 = 108 kmph

RRB Group D Mock Test - 33 - Question 65

A shopkeeper mixed two type of tea powders, type 1 and type 2, in the ratio 1:2 and sold the mixture at 20/- per kg. Find the profit percentage, if the cost price of type 1 and type 2 powders are 12/- and 18/- per kg respectively ?

Detailed Solution for RRB Group D Mock Test - 33 - Question 65

Let the quantity of Type 1 = k and that of Type 2 = 2k

Let x be the cost price of the mixture,

k(12)+2k(18) = (2k+k)(x)

12k+36k = 3kx

48k = 3kx

16 = x

CP = 16/- and SP = 20/-

Profit = SP - CP = 20 - 16 = 4/-

Profit % = \frac{4}{16}\times 100 = 25164​×100=25%

So the answer is option C.

RRB Group D Mock Test - 33 - Question 66

Find the LCM and HCF of 196 and 392 ?

Detailed Solution for RRB Group D Mock Test - 33 - Question 66

Here 392 = 2*196, Hence LCM is 392 and HCF is 196

7-15 = -2(mode)

-8 = -2(mode)

mode = 4

So the answer is option D.

on solving (1) and (2) we will get x = y = 0

So the answer is option A.

RRB Group D Mock Test - 33 - Question 76

The ratio of the present ages of A and B is 1:2. The sum of their ages 10 years from now will be 53. How old was A 10 years earlier?

Detailed Solution for RRB Group D Mock Test - 33 - Question 76

Let present age of A = x then that of B = 2x

Sum of their ages after 10 years = 53

(x+10)+(2x+10) = 53

3x = 33

x = 11

Present age of A = x = 11

Age of A before 10 years = x-10 = 11-10 = 1

So the answer is option D.

RRB Group D Mock Test - 33 - Question 77

RRB Group D Mock Test - 33 - Question 81

Two taps A and B can fill a bucket in 12 hours and 15 hours respectively. If both are opened and A is closed after 3 hours, how much more time would it take for B to fill the bucket?

Detailed Solution for RRB Group D Mock Test - 33 - Question 81

Let the capacity of tank = LCM of 12 and 15 = 60 units

Efficiency of tap A = 60/12 = 5 units/hr

Efficiency of tap B = 60/15 = 4 units/hr

If both the taps are opened for 3 hrs, part of the tank that would be filled = (5+4)*3 = 27 units

Remaining part = 60 - 27 = 33 units

Tap B alone can fill 33 units of tank in 33/4 = 8\frac{1}{4} hrs = 8 hrs 15 mins841​hrs=8hrs15mins

So the answer is option D.

RRB Group D Mock Test - 33 - Question 82

Choose the incorrect number in the given series:6, 13, 27, 55, 111, 221

Detailed Solution for RRB Group D Mock Test - 33 - Question 82

The logic used is as follows:

6*2 + 1 = 12+1 = 13
13*2 + 1 = 26+1 = 27
27*2 + 1 = 54 + 1 = 55
55*2 + 1 = 110+1 = 111
111*2 + 1 = 222+1 =223

As we can see, 221 is the incorrect term in the series. Therefore, option D is the right answer.

RRB Group D Mock Test - 33 - Question 83

Hence, option D is the correct choice.

RRB Group D Mock Test - 33 - Question 86

In a certain language 
‘call know before’ is coded as ‘gv qe nw’

Hence, option C is the correct choice.

RRB Group D Mock Test - 33 - Question 87

In a language, 
’Cars are blue roses’ is coded as ‘ta de ru la’
’ Roses are red’ is coded as ‘la ru fa’.
’red are blue’ is coded as ‘fa ru de’,

’roses’ and ‘are’ common to the first 2 sentences. Therefore, the code for ‘roses’ must be ‘lu’.
’are’ and ‘blue’ are common to the first and the third sentence. Therefore, the code for ‘blue’ must be ‘de’.

RRB Group D Mock Test - 33 - Question 92

A statement is given below. Check which of the following conclusions logically follows the statement given and choose the appropriate option:

The investigators of the scam recently unearthed the fact that even persons with impaired visions have been issued the license to drive by the corrupt officials.

Conclusion 1: Issuing licenses for people with impaired vision is a recent phenomenon.
Conclusion 2: People with impaired vision are not supposed to be issued a driving license.

Detailed Solution for RRB Group D Mock Test - 33 - Question 92

From the statement, we can infer that people with impaired vision are not supposed to be issued driving licenses. Therefore. Conclusion 2 definitely follows.

Conclusion 1 states that the phenomenon is recent. However, the statement only states that the unearthing of the scam is recent. We do not know how long the scam has been going on. Therefore, conclusion 1 cannot be said to follow the given statement. Therefore, option B is the right answer.

RRB Group D Mock Test - 33 - Question 93

A statement is given below. Check which of the following conclusions logically follows the statement given and choose the appropriate option:
 

Activists are protesting against the construction of dam since the lack of silt in the region after the dam will greatly reduce the yield of the region.

Conclusion 1: Silt is an essential element for crops to grow well.
Conclusion 2: Construction of dam obstructs the flow of silt in the river.

 

Detailed Solution for RRB Group D Mock Test - 33 - Question 93

In the statement, it has been given that the lack of silt will reduce the yield. Therefore, we can infer that silt is an essential element for crops. Conclusion 1 follows.

The statement mentions that there will be lack of silt only in the regions ’after’ the dam. Therefore, we can infer that the dam obstructs the flow of silt. Conclusion 2 follows.

Both the conclusions follow. Therefore, option C is the right answer.

RRB Group D Mock Test - 33 - Question 94

A statement is given below. Check which of the following conclusions logically follows the statement given and choose the appropriate option:
 

To protect the interests of the farmers, the government has proposed to construct cold storage facilities across the country. This will ensure that farmers do not give in to market pressures and can sell their produce at a nominal price, as they will not have to worry anymore about their goods getting perished.

Conclusion 1: Earlier, farmers gave in to market pressure since their goods were perishable.
Conclusion 2: Cold storage will ensure that farmers exploit the market and not the other way around.

Detailed Solution for RRB Group D Mock Test - 33 - Question 94

From the given statement, we can infer that farmers are being exploited since their produce is perishable. The line ‘as they will not have to worry anymore about their goods getting perished. 
’ implies that the goods getting perished is what that forced the farmers to accept sub par prices. Therefore, conclusion 1 follows.

Conclusion 2 states that farmers will exploit the market from now on. ‘Exploit’ is a strong word to use in this context. The given paragraph only states that farmers can fix a nominal price now which by no means can be equated to exploiting the market. Therefore, conclusion 2 does not follow.

Only conclusion 1 follows. Therefore, option A is the right answer.
