117
118
116
None of these

Answer

So, Option A

2.Some As are Bs and some Bs arc Cs. Which of the following is necessarily true?

I. Some As are Cs II. All Cs are As

Only (I) follows
Only(II) follows.
Both (I) and (II) follows.
Neither (I) nor (II) follow.

Answer

Hence, neither conclusion I nor II follow.

So, Option D

3. If H<G=J and J>K, then which of the following is necessarily true.

I. H>K II. G>K

only (I) is true.
only (II) is true.
both (I) and (11) are true.
Neither (I) nor (II) are true.

Answer

H < G = J > K

(I) H > K (Not sure) (II) G > K (True).

So, Option B

4.There are 40 people standing in a row. A is 12th from the left and B is 9th from the right. How many people are there in between A and B?

18
19
20

2. Some have suggested a correlation between not wearing polished shoes and being lethargic– that those who don’t polish their shoes are generally lethargic than those who do. This, however, is not the case. I work at the employment exchange and the majority of the applicants have polished shoes. Which of the following assumptions is made by the author of the argument?

Lethargy and polished shoes are learned behaviours.
People with polished shoes are never unemployed.
Lethargy has its origins in an individual’s family background.
People who apply for employment at the employment exchange are lethargic.

Answer

Assumption made by the Author of the argument is “Lethargy has its origins in an individual’s family background”.

So, Option C

Answer

sqrt(20-4) = sqrt(16) = 4

sqrt(45 – 20) = sqrt(25) = 5

sqrt(90 – 26) = sqrt(64) = 8

So, Option C

4. If DIP is coded as 172203, then what is the code for “TAKE”?

07152418
07142418
33142418
07142518

Answer

D	1	P
\|	\|	\|
4	9	16
Letter’s position

=> Code = (4 + 13), (9 + 13), (16 + 13) = 172229

Similarly,

= 1722(29 – 26) = 172203

T	A	K	E
\|	\|	\|	\|
20	1	11	5
Letter’s position

=> Code = (20 + 13), (1 + 13)(11 + 13),(5 + 13)

= 33 14 24 18 = (33 – 26) 14 24 18

= 07 14 24 18.

So, Option B

(d) Number of students who play atleast ones of cricket or soccer = 10 + 8 + 6 + 7 + 9 + 3 + 11 + 8 + 4 + 5 = 71

So, Option D

1.Two adjacent faces of a cube are painted red and out of the remaining sides, two opposite faces are painted green. The cube is then cut into 125 equal smaller cubes. How many smaller cubes will have at most two sides painted?

121
123
117
113

Answer

Total number of smaller cubes = 125.

Number of smaller cubes have 3 painted faces = 2.

Hence, number of smaller cubes have at most two painted faces = 125 – 2 = 123.

So, Option B

2. Prashant forgot his five-digit ATM pin. However he remembers that the ATM PIN has a cube of a number in the 3rd place and prime numbers in the first and the last places.
