MAT (Stage-1) Mock Test - 41

In all other number pairs, except in 31 : 97, the second number in the pair is obtained by adding 3 to the product of 4 and the first number in the pair.

In all the pairs, except 28 : 4, first number is obtained by adding 2 to the product of the second number and the number 2 greater than the second number.
[6 x (6 + 2)] + 2 = 50
[4 x (4 + 2)] + 2 = 26 (not 28)
[7 x (7 + 2)] + 2 = 65
[5 x (5 + 2)] + 2 = 37

All are prime numbers, except 27.

'Knowledge' (noun) is the odd one out because the other three are processes and also verbs.

The relation is n : n³.
The missing number is (11)³ = 1331

Sound is through ears. Similarly, touch is through skin.

'Patriotism' is quality of a 'citizen'. Similarly, 'concentration' is quality of a 'student'.

Touch strengthens into hold. Similarly, drizzle strengthens into downpour.

ABCD goes to the last 4 letters of the alphabet, but in reverse order.
(ABCD : WXYZ).
In the same way, EFGH goes to the 5^th - 8^th letter of the alphabet from the back, but in reverse order.

Multiply each term by 3/4 to obtain the next term.
21 1/3 x 3/4 = 16

16 x 3/4 = 12

12 x 3/4 = 9

9 x 3/4 = 27/4 = 6.75

The third term is the sum of first and second terms i.e. 21 + 34 = 55
The fourth term is the sum of second term and third term i.e. 34 + 55 = 89
The next term is 55 + 89 = 144
Therefore, missing term is 89 + 144 = 233

The pattern of the series is shown below.
2 + 13 = 15
15 + 13 x 2 = 15 + 26 = 41
41 + 13 x 3 = 41 + 39 = 80
80 + 13 x 4 = 80 + 52 = 132

The series is divided into three sub-series as shown below. First letter of each term moves one step forward, second letter moves three steps forward and third letter moves two steps forward to obtain corresponding letter of next term.
1. C, D, E, F, G
2. J + 3 = M; M + 3 = P; P + 3 = S; S + 3 = V
3. Q + 2 = S; S + 2 = U; U + 2 = W; W + 2 = Y
Therefore, missing term is 'GVY'.
