CISF Head Constable Mock Test - 6 - CISF Head Constable MCQ

• Prakash lives with his (or her) parents. So, at least 2 people are older than him (or her).
• Qureshi lives with 3 persons younger than him (or her).
• We also know Shabdeesh lives with his mother & is older than at least 2 people living with him. So, his gender is Male & his mother must be Qureshi.
• Now, Rajesh lives with his (or her) son & is not older than Shabdeesh. So, she must be female & wife of Shabdeesh & mother of Prakash.

Conclusions:

1. Qureshi (female) – Mother of Shabdeesh
2. Shabdeesh (male) – Son of Qureshi, Husband of Rajesh & Father of Prakash
3. Rajesh (female) – wife of Shabdeesh & mother of Prakash
4. Prakash (male or female) – son or daughter of Shabdesh & Rajesh

Qureshi is Prakash’s grandmother.

Solution: Observe that witnesses 1, 2, 3, 5 and 6 spoke about the colour of the car.
Now, two people were killed in the car accident and three were injured. Thus, five people should have been hit.
The statement of witness 6 corroborates this fact by saying that five people were hit and three were injured.
The statement made by witness 1 is incorrect as he says that three people were killed.
Therefore, witness 1 is in shock and all details provided by him are incorrect.
Therefore, the colour of the car is not red.
Hence, options 1 and 4 can be eliminated.
Similarly, the statement made by witness 5 is incorrect as he says that two people were injured.
Therefore, the colour of the car is not blue.
Hence, options 2 and 5 can be eliminated.
We can conclude that the colour of the car was green.
Hence, option 3.

Solution: Consider the solution to the previous question.
It is proved that the car was neither red nor blue, but was green in colour.
Therefore, witnesses 1, 3 and 5 are definitely in a shocked state.
Now, it is known that if a witness is in a state of shock, all details of his/her statement are false.
Therefore, witnesses 2 and 6 definitely gave correct information.
Now, since witness 2 gave correct information, the statement made by witness 4 and (consequently) that made by witness 7 is also true.
Hence, only 3 witnesses (i.e. witnesses 1, 3 and 5) were in a shocked state.
Hence, option 2.

All except Showel are tools for cutting

68 – 7 = 61; 61 – 7 = 54
124 + 7 = 131

44616 ÷ √? = 143 * 6
√?  = 2704

The statement asserts that a good singer always has a sweet voice and only good singers are invited in the conference. This implies that all those invited in the conference have sweet voice and those who do not have sweet voice are not invited. So, both I and II follow.

The statement clearly mentions that fulfilling the eligibility criteria and submitting the application before the stipulated date are both essential to avoid rejection. So, I follows. Also, since it is given that the candidates whose applications are rejected shall not be called for written test, so II also follows.

Following the final seating arrangement, we can say that G is sitting between H and V.
Hence, the correct answer is option D.

Common Explanation:
Reference:
O is sitting second to the left of U and third to right of H.
Inference:

Reference:
D and I are immediate neighbors of  each other but one of them is an immediate neighbor of O. 
V is sitting second to the right of B.
Inference:
Here, we can place D and I as follows:

Reference:
G is sitting second to the left of D.
Inference:
To fix these two positions, we will have to place D to the immediate right of H. Thus, we get the final arrangement as:

Following the final seating arrangement, we can say position of none of the members remains the same if we arrange all alphabetically as given in the question. 
Hence, the correct answer is option A.

Common Explanation:
Reference:
O is sitting second to the left of U and third to right of H.
Inference:

Reference:
D and I are immediate neighbors of  each other but one of them is an immediate neighbor of O. 
V is sitting second to the right of B.
Inference:
Here, we can place D and I as follows:

Reference:
G is sitting second to the left of D.
Inference:
To fix these two positions, we will have to place D to the immediate right of H. Thus, we get the final arrangement as:

Score of Chandan = 64 x 11 + 10 x 67 - 20 x 65 = 704 + 670 - 1300 
= 1374 -1300 = 74

The average rate of interest he pays is 186 x 100/1500 = 12.4%.

The average rate of interest being 12.4%, it means that the ratio in which the two amounts would be distributed would be 4:1 (using alligation). Thus, the borrowing at 12% would be Rs. 1200.

The data is insufficient as we do not know the time period involved.

odd numbers – x-2, x, x+2 ; even numbers – y-2, y, y+2
3x + 3y = 231
x + y = 77
(y – 2) – (x – 2) = 11
y – x = 11
x = 33, y = 44
sum of the largest even number and odd number = 46 + 35 = 81

Answer – d) 26% Explanation : Let total apples be 100 first day he throws = 50*20/100 = 10 apples next day he throws = 40*40/100 = 16 apples so total = 26

Volume of given figure = Volume of cone + Volume of cylinder
Radius of cone = Radius of cylinder, r = 7 cm
Height of cone = h₁ = 9 cm
Height of cylinder, h = 30 - 9 = 21 cm

Volume of figure = 462 + 3234 = 3696 cm³

Total expenditure of the Company during 2000
= Rs. (324 + 101 + 3.84 + 41.6 + 74) lakhs
= Rs. 544.44 lakhs.

Calculation:

Rise in 2015-16 = 53 – 51 = 2

Rise in 2016-17 = 65 – 53 = 12

Rise in 2017-18 = 76 – 65 = 11

Rise in 2019-20 = 68 – 58 = 10

Rise in 2020-21 = 73 – 68 = 5

∴ Maximum rise in production of wool with respect to previous year is in 2016-17

⇒ Total sales of all branches in 2010 = 49 + 83 + 57 + 52 + 79 = 320

∴ Required average = 320/5 = 64 

Calculation:

Number of students who scored more than 60% = 25 + 9 = 34

Total students = 2 + 2 + 12 + 25 + 9 = 50

Now, the required % = 34/50 × 100% = 68%
∴ 68% of total students scored more than 60%.

‘Most of these outfits continue to adopt earlier methodologies. These have proved no less effective than those followed by the IS. The terror attack on a mosque in North Sinai, Egypt in November this year, which killed over 230 persons, is one such example. In December, the TTP was responsible for a terror attack on an agricultural training institute in Peshawar, Pakistan. Differences among terror outfits, do not, however, preclude a complicated pattern of relationships when it comes to operational aspects.’

As per the highlighted fragments, statement I is incorrect.
