**Question 1:Â **In a certain code language, ‘GUM is coded as ‘49441169’. How will ‘WAX’ be coded as in that language?

a)Â 5291576

b)Â 8412525

c)Â 3611121

d)Â 2891400

**1)Â AnswerÂ (A)**

**Solution:**

G(7) = $7^2$ = 49

U(21) = $(21)^2$ = 441

M(13) = $(13)^2$ = 169

Similarly,

W(23) = $(23)^2$ = 529

A(1) = $(1)^2$ = 1

X(24) = $(24)^2$ = 576

‘WAX’Â is coded as ‘5291576’.

$\therefore$ The correct answer is option A.

**Question 2:Â **In a certain code language, ‘TAPEâ€™ is written as ‘SUZBOQDF’. How will ‘MOCK’ be written as in that language?

c)Â LOPQBCKL

d)Â KNNPBEBL

**2)Â AnswerÂ (B)**

**Solution:**

Similarly,

$\therefore$ The correct answer is option B.

**Question 3:Â **In certain code language, ‘FOX’ is coded as ‘108’ and ‘SOUP’ is coded as ‘148’. How will ‘UPSIDE’ be coded as in that language?

a)Â 528

b)Â 590

c)Â 385

d)Â 494

**3)Â AnswerÂ (A)**

**Solution:**

For the ‘FOX’,

[(27 – 6) + (27 – 15) +Â (27 – 24)] $\times$ number of letter

= (21 + 12 + 3)Â $\times$ 3

= 36Â $\times$ 3 = 108

For the ‘Soup’,

[(27 – 19) + (27 – 15) + (27 – 21) + (27 – 16)] $\times$ number of letter

= (8 + 12 + 6 +Â 11) $\times$ 4

= 37 $\times$ 4 = 148

Similarly,

For the ‘UPSIDE’,

[(27 – 21) + (27 – 16) + (27 – 19) + (27 – 9) + (27 – 4) +Â (27 – 5)] $\times$ number of letter

= (6 + 11 + 8 + 18 + 23 + 22) $\times$ 6

= 88 $\times$ 6 = 528

$\therefore$ The correct answer is option A.
