Sol. By reversing the letters, the new letter sequence is TSAISETNEDECCE. Clearly, E comes after D.
Q2. Choose the missing character from the given alternatives.
Sol. In 1st row:
48 ÷ 2 + 2 = 26, 48 ÷ 3 = 16
In 2nd row:
78 ÷ 2 + 2 = 41, 78 ÷ 3 = 26
In 3rd row:
88 ÷ 2 + 2 = 46, 88 ÷ 3 = 29.3
Q3. Shikha walks 10 km towards North. From there she walks 6 km towards South. Then, she walks 3 km towards East. How far and in which direction is she with reference to her starting point?
(a) 5 km South-West
(b) 7 km West
(c) 5 km North-east
(d) 7 km East
Clearly, Shikha moves from A, 10 km north-words upto B, then moves 6 km southwards upto C, turns towards East and walks 3 km upto D.
Then, AC = (AB – BC) = (10 – 6) = 4 km;
CD = 3 km.
So, Shikha’s distance from starting point A
=AD=√(AC^2+CD^2 )=√(4^2+3^2 )=5 km.
Also, D is to the North-east of A.
Q4. D the son-in-law of B, is the brother-in-law of A who is the brother of C. How is A related to B?
(d) Data inadequate
Sol. D is the son-in-law of B and brother-in-law of A. This means that B is the father/mother of D’s wife, and A is the brother of D’s wife. Thus, A is B’s son.
Q5. If 225 stands for 885, then 234 stands for
Sol. In the given system of coding, a number x is coded as (10 – x).
Thus, 2 is coded as (10 – 2) i.e. 8, 3 as (10 – 3) i.e. 7 and 4 as (10 – 4) i.e. 6. So, 234 stands for 876.
Q6. If MADRAS can be written as ARSMDA, how can ARKONAM be written in that code?
Sol. The word formed by first even number place letters then odd number place letters.
So, ARKONAM ->ROAAKNM
Q7. Choose the odd numeral pair/group in this question?
(a) 45, 27
(b) 30, 18
(c) 20, 10
(d) 15, 12
Sol. In all other pairs, the two numbers have 3 as the common factor.
Q8. In this question, certain pairs of words are given, out of which the words in all pairs except one, bear a certain common relationship. Choose the pair in which the words are differently related.
(a) Mercury : Sun
(b) Moon : Earth
(c) Star : Galaxy
(d) Wheel : Axle
Sol. In all other pairs, first moves about the second.
Q9. Choose the word which is least like the other words in the group.
Sol. Here, all except Peel are different forms of cooking. Hence, the answer is (b).
Directions (10-11): In each of the following questions, choose the number which is similar to the numbers in the given set.
Q10. Given set: 4718, 5617, 6312, 8314
Sol. In all the numbers, the product of the first and last digits is a multiple of the sum of the middle two digits.
Thus, 4 × 8 = 32 is a multiple of (7 + 1) i.e. 8,
5 × 7 = 35 is a multiple of (6 + 1) i.e. 7 and so on.
So, in 5412, 5 × 2 = 10 and (4+1) = 5
Q11. Given set: (14,42,13)
(a) (5, 32, 4)
(b) (10, 27, 9)
(c) (1, 16, 0)
Sol. In each set, 2nd number = (3rd number × 3 + 3)
and 1st number = (3rd number × 1 + 1)
Directions (12-13): In each of the following letter series, some of the letters are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.
Q12. aa _ abbb _ ccccd _ ddccc _ bb _ ba
Sol. The series is aaaa/bbbb/cccc/dddd/cccc/bbbb/a.
Q13. c _ ac _ aa _ aa _ bc _ bcc
Sol. The series is ccacc/aabaa/bbcbb/cc.
Directions (14-15): In each of the following questions, various terms of an alphabet series are given with one or more terms missing as shown by (?). Choose the missing terms out of the given alternatives.
Q14. BMX, DNW, FOU, ?
Q15. A, B, N, C, D, O, E, F, P, ?, ?, ?
(a) G, H, I
(b) G, H, J
(c) G, H, Q
(d) J, K, L
Sol. The given series may be divided into 2 groups:
I. A, B, C, D, E, F, ?, ? and II. N, O, P, ?
Clearly, the given series consists of two terms of I followed by one term of II. The missing terms in I are G and H while the missing term in II is Q.
