RRB NTPC (CBT I) Full Mock Test - 2 - RRB NTPC/ASM/CA/TA MCQ

Given:

Wrongly entered marks = 93 and Correct marks = 39
Difference in average = 1

Calculation:

The total increase in average marks due to the wrongly entered score.

Total increase in marks = 93 - 39 = 54

The total increase in marks is also equal to the difference in the average times the number of students. We know that the average increased by 1.

Total increase in marks = Difference in average × No of students

⇒ 54 = 1 × No of students

No of students = 54 / 1 = 54

∴ The total number of students in the class is 54.

Given:

Numbers: 15 and 25

Concept:

The Least Common Multiple (LCM) of two numbers is the smallest number that is a multiple of both.

Solution:

⇒ Find the prime factorization of 15: 3 × 5

⇒ Find prime factorization of 25: 5 × 5

⇒ LCM is the product of the highest powers of all prime numbers: 3¹ × 5² = 75

Therefore, the LCM of 15 and 25 is 75.

The correct answer is 0.2m/s².

Explanation:

Given:

Mass (m) = 500 kg

Force (F) = 100 N

We know that Force = Mass x Acceleration or F = m × a

⇒ 100 = 500 × a

⇒ a = 100/500

⇒ a = 0.2m/s².

Given :

First 90 km at a speed of 40 km/hr

Second 180 km at a speed of 60km/hr

Third 120 km at a speed of x km/hr

Formula Used :

Average Speed = Total distance travelled/Total time taken

Calculation :

According to question,

⇒

⇒ 520/9 = 390 × 4x/(9x + 12x + 480)

⇒ 520/9 = 390 × 4x/21x + 480

⇒ 10920x + 249600 = 14040x

⇒ 3120x = 249600

⇒ x = 249600/3120

⇒ x = 80

∴ The correct answer is 80.
