RRB Group D Mock Test - 1 - Question 1
Save

Ashu's mother was three times as old as Ashu 5 yrs ago. After 5 yrs, she will be twice as old as Ashu. How old is Ashu today?

Detailed Solution for RRB Group D Mock Test - 1 - Question 1

Let the present age of Ashu's mother and Ashu be x and y respectively.
(x - 5) = 3 (y - 5)
⇒ x - 5 = 3y - 15
⇒ x - 3y = - 10 .....(i)

After 5 years:
(x + 5) = 2 (y + 5)
⇒ x + 5 = 2y + 10
⇒ x - 2y = 5 .....(ii)

From (i) and (ii) we get x = 35 and y = 15 yrs

Hence, option B is correct.

Of the three numbers,the first is twice the second and the second is twice the third. The average of the three numbers is 21. find the largest number of the three.
Detailed Solution for RRB Group D Mock Test - 1 - Question 7
  • Let the third number be x.
  • Then, the second number is twice the third: 2x.
  • The first number is twice the second: 2 × 2x = 4x.
  • The average of the three numbers is 21:
  • (4x + 2x + x) / 3 = 21.
  • Simplifying:
  • 7x / 3 = 21
  • Multiply both sides by 3:
  • 7x = 63
  • Divide both sides by 7:
  • x = 9.
  • Therefore, the three numbers are 9, 18, and 36.
  • The largest number is 36.

In a code, CORNER is written as GSVRIV. How can CENTRAL be written in that code ?
Detailed Solution for RRB Group D Mock Test - 1 - Question 11

The word "CORNER" is coded as "GSVRIV."

To understand the code, let's look at the position of each letter in the alphabet and the transformation applied:

  • C (3rd letter) → G (7th letter)
  • O (15th letter) → S (19th letter)
  • R (18th letter) → V (22nd letter)
  • N (14th letter) → R (18th letter)
  • E (5th letter) → I (9th letter)
  • R (18th letter) → V (22nd letter)

It seems that each letter is shifted forward by 4 positions in the alphabet.

Now, to apply this shift to the word "CENTRAL":

  • C (3rd letter) → G (7th letter)
  • E (5th letter) → I (9th letter)
  • N (14th letter) → R (18th letter)
  • T (20th letter) → X (24th letter)
  • R (18th letter) → V (22nd letter)
  • A (1st letter) → E (5th letter)
  • L (12th letter) → P (16th letter)

Thus, "CENTRAL" will be written as "GIRXVEP" in the code.

Detailed Solution for RRB Group D Mock Test - 1 - Question 17

The figure may be labelled as shown.

Triangles :

The simplest triangles are IJQ, JKQ, KLQ, LMQ, MNQ, NOQ, OPQ and PIQ i.e. 8 in number. The triangles composed of two components each are ABQ, BCQ, CDQ, DEQ, EFQ, FGQ, GHQ, HAQ, IKQ, KMQ, MOQ and OIQ i.e. 12 in number.

The triangles composed of four components each are ACQ, CEQ, EGQ, GAQ, IKM, KMO, MOI and OIK i.e. 8 in number.

The triangles composed of eight components each are ACE, CEG, EGA and GAC i.e. 4 in number.

Total number of triangles in the figure = 8 + 12 + 8 + 4 = 32.

Squares :

The squares composed of two components each are IJQP, JKLQ, QLMN and PQNO i.e. 4 in number.

The squares composed of four components each are ABQH, BCDQ, QDEF and HQFG i.e. 4 in number.

There is only one square i.e. IKMO composed of eight components.

There is only one square i.e. ACEG composed of sixteen components.

Thus, there are 4 + 4 + 1 + 1= 10 squares in the given figure.
