Answers
1-Ans.(a)
Sol. K’ s value from end side in alphabet is 16
P’s value from starting is 16
By multiplying both its 256
Similarly H’s value from end side is 19
S’s value from starting is 19
By multiplying both its 361 2-(c)

Sol. 17² = 289/2 = 144.5

13² = 169/2 = 84.5

3-(b)
Sol. INDIA’s National bird is PEACOCK
USA’s National bird is Bald Eagle4-(c) 
Sol. For human food is energy giving material
For automobiles fuel is the energy source 5-(d)
Sol. In the group RANDOM, the order of letters is put according to alphabetical sequence to get ADMNOR. Similarly, PROJECT can be converted to CEJOPRT6-(a)
Sol. 

Similarly, UXA-> EHK7-(d)
Sol. Since Menu is a way to depict different types of food available, similarly we represent different types of books available through a Catalogue8-(c)

Sol. 36 is the product of the digits of the square of 7 (7²=49=4*9=36). Similarly, for, the value will be 8.

9-(a)
Sol. 30 and 42 are numbers formed by 5*6 and 6*7. So, since, 72 is 8*9, next should be 9*10. 10-(a)
Sol. CAMP is coded by writing its equivalent position from other end of the alphabet sequence. Similarly, HZOG was coded from SALT. 11-(c)

Sol. 8² = 64,  8+4 = 12

12² = 144

Similarly, 16² = 256,  16+4 = 20

20² = 400

12-(d)
Sol. ACEG is coded by writing its equivalent position from other end of the alphabet sequence. Similarly, HJLN was coded from SQOM. 13-(b)

Sol. Q---+3--àT

T----+1--àU

Then U---+14-- -à I

Same pattern follow by L and M as T and U.

So, BEF -> TWX

14-.(c)
Sol. 

Similarly, IR-> MN15-(a)

Sol. 3² -1 = 8

3³ +1 = 28

Similarly,  4²-1 = 15

4³ + 1 =65
