49-32= 17

70-49=21

?- 70= 25

3. In a certain code language if the word ‘MUSEUM’ is coded as ‘LSPAPG’, then how
will the word ‘PALACE’ be coded in that language?

a. OYIWXY

b. OYIXYW

c. IYXYWO

d. YXWYOI

Word: P A L A C E
Logic: -1 -2 -3 -4 -5 -6
Code: O Y I W X Y

4. If DELHI is coded as 73541 and CALCUTTA as 82589662, how can CALICUT be coded?

a. 5279431

b. 5978213

c. 8251896

d. 8543691

Answer : Option C

The alphabets are coded as follows:

D E L H I C A U T

7 3 5 4 1 8 2 9 6

So, in CALICUT, C is coded as 8, A as 2, L as 5, U as 9 and T as 6. Thus, the code
for CALICUT is 8251896.

5.In a certain code language, if the value of CONTRACT = 56 and ‘GROWTH’ = 30, then
what is the value of DISTRIBUTION?

a. 130

b. 132

c. 140

d. 142

Answer : Option B
Explanation :

Number of letters in the word CONTRACT = 8 and 8 x 7 = 56.

Number of letters in the word GROWTH = 6 and 6 x 5 = 30.

Similarly, DISTRIBUTION => 12 and 12 x 11 = 132.

6. In a certain code language, if the value of ‘BLOCK’ = 13 and ‘CURTAIN’ = 27,
then what is the value of the word ‘SCIENCE’?

a. 32

b. 36

c. 38

d. 34

Answer : Option C
Explanation :

In this product of the digits in the place-values of the letters as
per the alphabet is obtained first and then added i.e, BLOCK

=> B = 2

L = 12 => 1 x 2 = 2

O = 15 => 1 x 5 = 5

C = 3

K = 11 => 1 x 1 = 1

Now (2 + 2 + 5 + 3 + 1) = 13.

So, BLOCK = 13.

Similarly, SCIENCE = 38.

7. 1.5, 3, 5.5, 9, 13.5, 19, …

a. 81

b. 15.5

c. 21.5

a. 104th

b. 105th

c. 106th

d. 64th

Answer : Option C
Explanation :
Clearly, 5+3= 8, 8+3= 11, 11+3= 14,….

So this is an A.P series in which a=5, d=3.

Let the number of the terms be n

Then, 320= 5+(n-1)*3; 3n=318; n=106

9. In the series 5, 10, 20, 40,….what will be the 10th term?

a. 1280

b. 2560

c. 1820

d. 2650

Answer : Option D
Explanation :

This is an G.P series in which a= 5; r= 2

10th term= ar(n-1) = 5*2 (10-1) = 5*2 9 = 2560

10. In a certain code language, if the value of 14 x 15 = 25 and 26 x 42 = 64, then
what is the value of 73 x 31 = ?

a. 100

b. 110

c. 90

d. 120

Answer : Option A
Explanation :

14 x 15 = 14 + 15 = 29 and 29 – 4 = 25.

26 x 42 = 26 + 42 = 68 and 68 – 4 = 64.

Similarly, 73 x 31 = (73 + 31) – 4 = 104 – 4 = 100.
