Solutions​​ 

1-b​​ 

Soln.​​ A person who studies and collects butterfly is​​ Lepidopterist. Similarly coma a person who collects postcard is called deltiologist.

2 -a

Soln. BLEND​​ is written as ENHPG (B+3 =E​​ , L +2= N, E+3=H,​​ N+2=P,​​ D+3 =G). HERE 1st​​ alphabet is increasing by​​ +3 ​​​​ &​​ next letter is increasing by +2 and so on.​​ Similarly, WINNER is written​​ ZKQPHT​​ (W+3,I+2,N+3,N+2, E+3,R+2)

3-a

Soln.​​ V is coded​​ as 44. i.e Rank of V is doubled. (22×2). Similarly, FAT (F-6,​​ A-1, T-20)

(6+1+20) ×2 =54

4-a

Soln.​​ Last alphabet of all series in increased​​ by 1st​​ alphabet + 6 expect​​ the 1st​​ option.

    • H+5=M

    • P+6=V

    • D+6=J

    • J+6= P

5-b

Soln.​​ Difference between 1st​​ & 3rd​​ digits is 2​​ in all above options expect b.

    • 5-3=2

    • 3-2=1

    • 9-7=2

    • 7-5=2

6-d

Soln.​​ GATE ~HXYX​​ ​​ (G+1= H,​​ A-3=X ,T+5= Y,​​ E-7=X)

From the following segments of series from ever we can arrange the next one as​​ 

SINK ~ TFSD​​ (S+1 =T, I-3 =​​ F and so on.)

7-a​​ 

Soln. (4, 14,44)​​ 

​​ (4×3)​​ +​​ 2=14, (14×3)+2 =44

Similarly,​​ 

(11, 35,​​ 107)

(11×3)+2=​​ 35, 35×3)+2=107

Hence, the required ​​ answer in a.

8-d

Soln. (4, 152, 6)​​ cube of 6​​ – cube of 4.​​ 

216-64=152​​ Similarly on option d cube of 6 – cube of 2.

216-8 =208.

9-d​​ 

(7 : 85)​​ 7×7​​ +(6×6)*​​ = 49+36=85 (7-1=6)*​​ Similarly, 8 : 113 = 8×8 + (7×7)* =64+49= 113​​ 

*(8-1=7)

10-d

Soln.​​ Chicken pox also known as Varicella,​​ is a highly contactless disease caused by the initial infection with VZU. SIMILARLY​​ ringworm is also a common infection of the skin and nails that is caused by fungus.
