MAT (Stage-1) Mock Test - 47

Except 1825, the rest are squares of 15, 25 and 35.

Except 426, rest of them are odd numbers.

In all the numbers, except 4009, sum of first three digits is equal to the fourth digit.

4 + 3 + 0 = 7

5 + 3 + 0 = 8

5 + 1 + 0 = 6

Hence, 4009 is the odd one out.

Option 1: D + 2 = F, F + 2 = H, H + 2 = J

Option 2: K + 2 = M, M + 2 = O, O + 1 = P

Option 3: R + 2 = T, T + 2 = V, V + 2 = X

Option 4: Q + 2 = S, S + 2 = U, U + 2 = W

KMOP is different from others.

(1) JK (L) MN (Gap of 1)

(2) ST (UV)WX (Gap of 2)

(3) XY (Z) AB (Gap of 1)

(4) EF (G) HI (Gap of 1)

In the groups, four consecutive letters are given in alphabetical order, with position of second and third letters interchanged. In STUV, all letters are in correct order, hence it is the odd one.

4 : 60 : : 5 : ?

Here, the pattern is n : (n³ - n).

⇒ 4³ - 4 = 60

⇒ 5³ - 5 = 125 - 5 = 120

Every letter is replaced by two letters which are its predecessor and successor in the English alphabet. For example: B is coded as AC.
Hence,

BONUS : (AC)(NP)(MO)(TV)(RT)

Car is parked at garage and aeroplane is parked at hangar.

15 - 14 = 1, which is 1².

23 - 15 = 8, which is 2³.

32 - 23 = 9, which is 3².

96 - 32 = 64, which is 4³.

121 - 96 = 25, which is 5².

Therefore, the missing term is 121.

7, 9, 19, 45, 95, ?

9 - 7 = 2

19 - 9 = 10

45 - 19 = 26

95 - 45 = 50

New series: 2, 10, 26, 50, ?

10 - 2 = 8

26 - 10 = 16

50 - 26 = 24

Every next element is increasing by 8.

So, the next element in the second series will be 50 + 32 = 82

Therefore, 95 + 82 = 177

Hence, the missing term is 177.

The pattern is:

240 ÷ 1 = 240

240 ÷ 2 = 120

120 ÷ 3 = 40

40 ÷ 4 = 10

10 ÷ 5 = 2

Hence, missing term is 240.

The pattern is:

M - 1 = L, L - 1 = K, K - 1 = J, J - 1 = I

E - 1 = D, D - 1 = C, C - 1 = B, B - 1 = A

S - 1 = R, R - 1 = Q, Q - 1 = P, P - 1 = O

Missing term is JBP.
