Dear Bankersdaily Aspirants,

IBPS RRB PO & Office Assistant 2018 Preliminary Examination starts from 11th August, 2018. The IBPS RRB Exam 2018 is one of the most expected exam of the year. The reason for the consummate expectation is different from that of the others.

The number of candidates attending the IBPS RRB PO & Office Assistant is high when compared to the other exams like SBI & Insurance Exams. The other important factor is that , no English section is there in the preliminary examination of the IBPS RRB PO & Assistant Exams. This is really a boost to the candidates as many of the aspirants couldn’t get the requisite marks in the English section and this exam is the best bet for the aspirants.

**Explanations**

Q.1) a

= 40 + 130 – 5

= 165.

Q.2) d

=

Q.3) b

20% of 520 = 104

25% of 700 = 175

16% of 300 = 48

Then, 104 + 175 – 48 is = 279 – 48 = 231.

Q.4) e

=

Q.5) a

25% of 320 = 80

20% of 370 = 74

80 – 74 = 6

6 =

Q.6) c

Differences = 16, 25, 36, 49

In this series, the next value = 64

Then 64 + 127 is = 191.

Q.7) e

Difference between the base value = 1, 2, 3, 4, 5, 6….

Q.8) b

Difference = 10, 15, 22, 31, 42…

Difference of difference = 5, 7, 9, 11, 13

42 + 13 = 55

Then, 55 + 151 is = 206.

Q.9) d

The series is =

787.5

Q.10) a

5 +5 = 8120 + 5 = 8125

Q.11) a

Work efficiency of M and O = 1.5 : 1

Then, the number of days required by M and O = 1 : 1.5

M alone can do the work = = 40 days.

M and N do the work in 30 days.

N alone can do the work =

Q.12) b

Girls and boys = 4 : 7 = 24 : 42

Then, the number of village boys = 42 – 27 = 15

The ratio of village boys to village girls = 3 : 4 = 15 : 20

Then, the number of non-village girls = 24 – 20 = 4.

Q.13) b

Ratio of X, Y and Z

X Y Z

6 5

4 5

————————-

24 20 25

————————-

Difference between X and Z = 25 – 24 = 70

Then X + Y + Z = 24 + 20 + 25 = 69

Then total = = 4830.

Q.14) c

Perimeter of a rectangle = Circumference of a Circle.

Perimeter of the rectangle = 2(l+b) = 2 (12 + 9) = 42

Volume of a Cylinder = 2

2

2

Q.15) e

Total age =

Age of first 30 =

Age of last 35 =

Remaining age = 3150 – (1410 + 1400) = 340

Average age of remaining passengers =

Q.16) e

By the given information, we get only the total age of Father and Mother. We don’t know about their individual ages. So, we could not find the answer.

Q.17) b

=

Q.18) a

70% of 490 is = 343.

Difference between Si and Ci = 343

=

Then 100% =

Q.19) d
