RRB Group D Mock Test - 37 - RRB Group D / RPF Constable MCQ

Let CP = x

(1-0.2)(x) = 20000

(0.8)(x) = 20000

x = 25000/-

So the answer is option B.

Total attendance in 5 days = 678*5 = 3390

Attendance in 1st day + attendance in last 4 days = attendance in 5 days

x + 4(679) = 3390

x + 2716 = 3390

x = 674

So the answer is option D.

Total distance = 150km

Distance covered by him in 2 hrs = 45*2 = 90km

Remaining distance = 150-90 = 60km

So the answer is option C.

So the answer is option B.

H.C.F of fractions = H.C.F of numerators / L.C.M of denominators = (HCF of 1, 2, 3)/(LCM of 2, 3, 4) = (1)/(12) = 1/12

Let total work = LCM of 8 and 12 = 24 units

Efficiency of P&Q; = 24/8 = 3

Efficiency of Q = 24/12 = 2

Then efficiency of P = 3-2 = 1

P alone can complete 24 units of work in 24/1 = 24 days

So the answer is option A.

Length of rectangle = 9 cm

Breadth = side of square = √36 = 6 cm

Perimeter = 2(l+b) = 2(9+6) = 30cm

So the answer is option B.

Lateral surface area = 2h(l+b) = 2(4)(6+8) = 112sq.cm

Cost of painting = 112*1.5 = 168

So the answer is option A.

SP = 2500

Profit = 100

CP = SP - Profit = 2500 - 100

Slope of given line = 5/3

Slope of a line perpendicular to given line = -3/5

So the answer is option C.

Let it's edges are 2x, 3x, 4x

Surface area = 468

B is the first consonant and A is the first vowel.
C is the second consonant and E is the second vowel.
D is the third consonant and I is the third vowel.

Therefore, the next term must be composed of the fourth consonant and the fourth vowel - F and O respectively. Therefore, option C is the right answer.

Kiwi, Ostrich and Emu are flightless birds. Peacock can fly. Therefore, option D is the right answer.

The order in which these words will appear in a dictionary:
3. nefarious
1. nemesis
2. neology
4. neonatology

The series follows the following pattern n³−n²

Diffuser has 2 F’s. SCHADENFREUDE has only one F. Clearly, DIFFUSER cannot be made by shuffling the letters of SCHADENFREUDE. Hence, option D is the right answer.

The code for a word is the product of the position of the letters of the word in the alphabetical series.

DRY - 4*18*25 = 1800
BAT - 2*1*20 = 40

Let us evaluate the options using the same logic.

GATE - 7*1*20*5 = 700
DEBT - 4*5*2*20 - 800
BEED - 2*5*5*4 - 200
DATE - 4*1*20*5 - 400
Therefore, option C is the right answer.

Let us replace the symbols with the actual operators.

13 - 13 / 3 - 63 * 9 + 2 -5 = 13 * 13 + 3*63/9 - 2*5

Applying BODMAS rule, we get, 169 + 3*7 - 10 = 180
Therefore, option B is the right answer.

Each number is used only once and the sums of numbers along both the diagonals are equal.
6 + z + y = 2 + 8 + z
=>y = 4
6 + 1+ 8 = 6 + z + 4
=> z = 5 and x = 3.
(x,y,z) = (3,4,5).
Therefore, option A is the right answer.

The given statements can be expressed diagrammatically as follows without violating any of the conditions.

 

Shrubs that are herbs cannot be trees as no herb is a tree. Therefore, conclusion I does not follow.
Trees and herbs can be 2 disjoint subsets of Shrubs. Therefore, conclusion II follows.

Only conclusion II follows. Therefore, option B is the right answer.

Belgium is famous for glass products. Similarly, Italy is renowned for its marbles. Therefore, option C is the right answer.
