RRB NTPC Previous Year Paper (Allahabad) - 2013 - RRB Group D / RPF Constable MCQ

22 boys are standing in front of Kunal in a Queue 12 boys are standing to the back of Rohit
Total boys = 30.
So, rank of Kunal in the queue is 22+1 = 23
Rank of Rohit in the queue is 30 - 12 = 18
Hence, the number of boys between Rohit and Kunal in the queue is 23 - 18 - 1 = 4

There is only one a between the 7th 'a' from the left and 7 th 'a' from the right.

a a b a b a a b a b a a a b b a b a b b a a a a

If A stands for ‘+’, B stands for ‘-’, C stands for ‘x’ and D for ‘÷' then

There are 7 years between the two except two of them are leap years.

In a normal year, there are 365 days. 365 when divided by 7 leaves a reminder of 1. So, 1 July of a year and 1 July of the previous year are one weekday apart. If it is a leap year, 1 July of a year and 1 July of a previous year are separated by 2 weekdays. So, If July 1, 1977 was a Friday, 1st july 1976 is a Thursday and 1st july 1975-tuesday 1st july 1974-monday 1st july 1973-sunday 1st july 1972-saturday 1st july 1971-thrusday 1st july 1970- wednesday

The given equation means P is the father of Q and Q is the sister of R. So, P maybe the father of R.

In 278 and 853, 8 and fast are common.

In 853 and 376, 3 and come are common

The conclusion can be drawn from "none but stout men are players" since it implies that all players have to be stout.

Campaign is generally related to a military manoeuvre. Others are unrelated to military.

The opposite of Natural is artificial. The opposite of spontaneous is calculated.

301 is divisible by 7 (43 times)

497 is also divisible by 7 (71 times)

So, the required sum is

7 ( 43 + 44 + .... + 71)

= 7 x (sum of numbers upto 71 - sum of numbers upto 42) = 7 * [(71x 72/2)-(42 x 43/2)]

= 11571

5p + 4e = 13

9p + 5e = 19

solving for p, we get p = 1

e = 2

So, 6 pencils and 3 erasers cost

6 x 1 + 3 x 2 = 12

If a₁, a₂.........a₇ are different positive integers taking one value at a time from 1,2,........7. The number (a₁-1) (a₂-2)......(a₇ -7) will always be zero as one of the numbers will be equal to 1, 2, 3.... 7.

88935 can be written as 5929 x 15

5929 is the square of 77

So, the answer is 15

The area of the bigger rectangle is 18 x 13

The are of the smaller rectangle is 16 x 11

The required value is 18 x 13 - 16 x 11 = 58 sq.m

If the difference between the digits has to be 4, only 73 and 95 qualify. Of these 73 leaves a remainder of 3 and not 4 when divided by 7. So, the answer is 95.

Number of stations in 350 kilometers = 350/ 42 = 50/6 = 8 stations.

Time stopped at stations = 8 x 5 = 2/3 hrs

Time taken for travel = 350/72 + 2/3 = 5 hours 31 minutes 40 seconds
