Column-I	Column-II
Drink fruit juice	tee see pee
Juice is sweet	see kee lee
He is intelligent	lee ree mee

pee

see

tee

kee

Solution

"Juice" is common in the first and second rows of Column-I and is coded as "see".
"Is" is common in the second and third rows of Column-I and is coded as "lee".
Therefore, "sweet" is coded as "kee".

Question 17
1 / -0

Which of the following words will fall in the second position if all of them are arranged alphabetically as in a dictionary?

A
Cruise

B
Crupper

C
Crusade

D
Crumb

Solution

We can see that the first three letters of the given words are same. So, comparing the 4^th letter in each word, the order is 'i, m, p, s', which means 'crumb' will be the second word out of all the given words after the arrangement.
Question 18
1 / -0

The position of Mansi from the right end of a row is 18. What would be her position from the left end, if there are 40 students in a row?

A
20

B
21

C
22

D
23

Solution

Total students = 40
So, position of Mansi from the left end = 40 - (18 - 1) = 23^rd
Her position would be 23^rdfrom left end.
Hence, answer option 4 is correct.
Question 19
1 / -0

Directions: There are eight people A, B, C, D, E, F, G and H sitting around a circular table facing the centre. B is sitting second to the left of G, who is sitting third to the right of F. Only E is sitting between A and C. C is sitting third to the left of B. Only one person is sitting between E and H.

Which of the following is correct?

A
D is sitting third to the left of H.

B
F is sitting third to the left of G.

C
C is sitting third to the left of D.

D
H is sitting second to the right of C.

Solution

According to the instructions:
All of them are facing center.
(1) B is sitting second to the left of G, who is sitting third to the right of F.
(2) C is sitting third to the left of B

From further instructions:
(3) Only E is sitting between A and C.(4) Only one person is sitting between E and H.

D will be sitting to the immediate right of B and immediate left of G.

Therefore, "F is sitting third to the left of G" is correct.
