RRB NTPC (CBT I) Full Mock Test - 9 - RRB NTPC/ASM/CA/TA MCQ

A spends Rs. 200 for every Rs. 20 spent by B.
⇒ Ratio of expenditures of A and B = 10 : 1.
B spends Rs. 400 for every Rs. 150 spent by C
⇒ Ratio of expenditures of B and C = 8 : 3
A : B = 10 : 1 = 80 : 8
B : C = 8 : 3
Thus, A : B : C = 80 : 8 : 3
Ratio of their expenditures = 80 : 8 : 3

The series is:
(1)² = 1
(2)² = 4
(3)² = 9
(4)² = 16
(5)² = 25
(6)² = 36
36 is the missing term.

Shweta is now (10 + 18) steps, i.e. 28 steps away from her initial position.

Let the salaries of A, B and C be Rs. 2x, Rs. 3x and Rs. 5x, respectively.
By the condition given in the question,
5x – 2x = Rs. 600
3x = Rs. 600
So, B's salary = Rs. 600.

Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde.

L.C.M. of 8, 12, 20 = 120
So, the required number will be of the form 120(k) + 1.
Check values of k = 1, 2, 3, 4 for divisible by 13.
(i) k = 1, N = 120 x 1+ 1 = 121; this is not divisible by 13.
(ii) k = 2, N = 120 x 2 + 1 = 241; this is not divisible by 13.
(iii) k = 3, N = 120 x 3 + 1 = 361; this is also not divisible by 13.
(iv) k = 4, N = 120 x 4 + 1 = 481; this is divisible by 13.
For k = 4, the number obtained is divisible by 13.
Thus, the required number (N) is 481.

The Venn diagram representing the given situation is as follows:

Number of people belonging to only one group = 6 + 2 + 3 = 11

Prime Minister Narendra Modi, in July 2024, achieved a significant milestone by becoming the most followed world leader on the social media platform X (formerly Twitter), with over 100 million followers.
Globally, PM Modi outpaced other world leaders on the platform. For instance, US President Joe Biden has 38.1 million followers, Dubai's ruler HH Sheikh Mohammed has 11.2 million, and Pope Francis has 18.5 million.

Third term is the sum of the first two terms; fourth term is the sum of the second and third terms; fifth term is the sum of the fourth and third terms, and so on.
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13
Missing term = 13

The Fundamental Rights in its basic nature are rights enforceable by the Courts of Law and any act of State or Law that violates fundamental rights are ultra vires.

If we compare 3/8 = 219/584  and 19/73 = 152/584, we see that 3/8 > 19/73.
If we compare 3/8 = 117/312 and 17/39 = 136/312, we see that 17/39 > 3/8.
If we compare 17/39 = 799/1833 and 29/47 = 1131/1833, we see that 29/47 > 17/39.
So, combining all the inequalities, we get:
19/73 < 3/8 < 17/39 < 29/47
Thus, option 2 is correct.

Let the article's cost be Rs. X for A.
A's selling price = B's cost price = X × 1.2
B's selling price = C's cost price = X × 1.2 × 1.15
Now, X × 1.2 × 1.15 - X = 190
⇒ 1.38X - X = 190
⇒ 0.38X = 190
⇒ X = (190 x 100)/38 = Rs. 500
A's profit = 20% of 500 = Rs. 100

The figure given below shows the allotment of flats. Each person is represented by the initial letter of his name.

Evan and Chitra are exactly opposite to each other.

In April 2024, Amitabh Bachchan was honoured with the Lata Deenanath Mangeshkar Award for his exceptional contributions to Indian cinema. The award ceremony took place on April 24 at the Deenanath Mangeshkar Natyagriha in Mumbai.

Let x be the total distance travelled.
1200 = (2/5)x
x = (1200/2)  × 5
x = 3000 km
Distance travelled by car = (1/3)x = (1/3)x3000 = 1000 km
Distance travelled by air = (2/5) × 3000 = 1200 km
Distance travelled by train = 3000 – 2200 = 800 km

Both A and R are true and R is the correct explanation of A.
This can be proven using this specific knowledge. Green plants are green because they contain a pigment called chlorophyll. In the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.

The proper sequence is:
(Q) The climate of India (S) comprises a wide range of (P) weather conditions across a vast geographic (R) scale and varied topography.
So, QSPR is the correct answer.

AB = EC = 12 m
CD = BD - BC = 20 - 15 = 5 m
In triangle ECD, we have
ED² = CD² + CE²
⇒ ED² = 5² + 12²
⇒ ED² = 25 + 144
⇒ ED² = 169
⇒ ED = 13 m
Thus, the distance between their tops is 13 m.

As per the given Venn diagram, only conclusion A is correct.

In Δ GEF and Δ GCD, we have
∠EFG = ∠GDC (Alternate angles)
∠EGF = ∠CGD (Vertically opposite angles)
Δ GEF ~ Δ GCD (by AA similarity)
Thus,
GE/CG = EF/CD 
or,
6/12 = EF/16
or, EF = 8 cm

If a = 2;
a/b = 1/4 ... (i)
⇒ 2/b = 1/4 
⇒ b = 8
Now, given,
b/c = 1/8
⇒ 8/c = 1/8
⇒ c = 8 x 8 = 64
This is the correct answer

Let the amount of work done by A is W.
Then, the amount of work done by B is 10 W.
Total work done by A in 1 day = 1/36
Now, since B is 20% more efficient than A, then the total work done by B in 1 one day is 20% more i.e. 120% of A i.e. (120/100) x (1/36) = (1/30) 
Total work done that requires 10 times the effort is 1/30.
Total work to be done is 10 W + W = 11 W.
Let n be the number of days required to complete the work. Then,

(66n/1080) = 11
n = (1080x11)/66
n = 180

So, X is Y's uncle.

In the figure, a plane mirror is kept in front of a clock.

It is clear from the figure that:
If actual time = 3:25,
Then, after reflection, the time would be = 8:35
