RRB JE CE (CBT I) Mock Test- 8 - Question 21

How many whole numbers are there between 52 and 356 which are exactly divisible by 6?

A. 49
B. 51
C. 53
D. 55

Detailed Solution for RRB JE CE (CBT I) Mock Test- 8 - Question 21

First whole number which is divisible by 6 between 52 and 356 is 54

Last whole number which is divisible by 6 between 52 and 356 is 354

So, by using AP formula:-

Last term = first term + (number of terms-1) × Common difference

354 = 54 + (n-1) × 6

300 = (n-1) × 6

50= (n-1)

So, n =51

Therefore,

There are 51 whole numbers between 52 and 356 which are exactly divisible by 6.

RRB JE CE (CBT I) Mock Test- 8 - Question 22

Directions

In the following problems, there is one question and some statements given below the question. You have to decide whether the data given in the statements is sufficient to answer the question. Read all the statements carefully and find out which of the statements is/are sufficient to answer the given question. Choose the correct alternative for each question.

Question:

What will be the total weight of 10 poles, each of the same weight ?

Statements:

I. One-fourth of the weight of each pole is 5 kg.

II. The total weight of three poles is 20 kilograms more than the total weight of two poles.

A. I alone is sufficient while II alone is not sufficient
B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Both I and II are sufficient

Detailed Solution for RRB JE CE (CBT I) Mock Test- 8 - Question 22

From I, we conclude that weight of each pole = (4 x 5) kg = 20 kg.

So, total weight of 10 poles = (20 x 10) kg = 200 kg.

From II, we conclude that:

Weight of each pole = (weight of 3 poles) - (weight of 2 poles) = 20 kg.

So, total weight of 10 poles = (20 x 10) kg = 200 kg.

RRB JE CE (CBT I) Mock Test- 8 - Question 28

A shopkeeper offer Rs. 19% discount on a mobile phone with a marked price of Rs. 7400. If he still earns a profit of Rs. 500, what is the cost price of the phone?

A. Rs. 6900
B. Rs. 8340
C. Rs. 5494
D. Rs. 4950

Detailed Solution for RRB JE CE (CBT I) Mock Test- 8 - Question 28

Selling Price = Marked Price × (100-Discount) %

Therefore,

SP = 7400 × (100-19) %

SP=7400×81/100

SP = 5994

So,

Cost Price = Selling Price - Profit

CP = 5994-600

CP = 5494

RRB JE CE (CBT I) Mock Test- 8 - Question 42

Six persons A, B, C, E, F and G, are having different weights. C is lighter than only one person, who is neither E nor B. A is the lightest one and F is not the heaviest one. E is lighter than B. F is lighter than at least three persons. B is lighter than how many persons?

A. One
B. Two
C. Three
D. Either (a) or (b)

Detailed Solution for RRB JE CE (CBT I) Mock Test- 8 - Question 42

C is lighter than only one person, who is neither E nor B.

Thus, we get,

__ < __ < __ < __ < C < __

since,

A is the lightest one and F is not the heaviest one.

Thus, G is the heaviest.

We get,

A < __ < __ < __ < C < G

Now,

E is lighter than B.

F is lighter than at least three persons.

We get two possibilities:

A < E < F < B < C < G

A < F < E < B < C < G

In both the possible cases, B is lighter than 2 persons. Hence, option (b).

C. If the data in Statement I alone or in Statement II alone is sufficient to answer the question
D. If the data in both the Statements I and II together are not sufficient to answer the question.

Detailed Solution for RRB JE CE (CBT I) Mock Test- 8 - Question 43

Using statement I alone

T< P < Q

No information is given about S and R.

Thus, the question cannot be answered using Statement I alone.

Using statement II alone:

P > S > R

No information is given about Q and T.

Thus, the question cannot be answered using Statement II alone.

Using both statements I and II together:
