Question 9: If in a certain language, ‘oka peru’ means ‘fine cloth’, ‘meta lisa’ means ‘clear water’ and ‘dona lisa peru’ means ‘fine clear weather’, what word in that language mean ‘weather’?

b) dona

c) oka

d) peru

Question 10: In a certain code, ‘GROWTH’ is written as ‘HQPVUG’ and ‘FOUR’ is written as ‘GNVQ’. How is ‘PROBLEMS’ written in that code?

a) QQPAKDNR

b) QQNCMDNR

c) OQPAMDNR

d) QQPAMDNR

The code uses the letters in the alphabetical series in an inverted fashion. For example: A is used in the place of Z, B in the place of Y, etc. Also they are inverted. So, The last letter comes first in the code. So, I is replaced with R, K with P, M with N and O with L. The code is LNPR.

Each letter of the word JOVIAL follows the pattern +3 and +1 alternatively .

J + 3 = N

O + 1 = Q

V + 3 = Z

I + 1  = K

A + 3 = E

L +  1 =  N

Similarly, FIGURE is JKKWVG

bir le nac’ means ‘green and tasty’,……………..(1)

‘pic nac hor’ means ‘tomato is green’…………….(2)
‘coc bir hor’ means ‘food is tasty’………………..(3)

from (1) and (2) nac = green

from (1) and (3) bir = tasty

le = and

from (2) and (3) hor = is

pic = tomato

hor pir bic means ‘tomato is tasty’

tir sil fit’ stands for ‘nice big home………………(1)

‘kon hit sil’ stands for ‘home is good’……………(2)

‘bdf zkr kon’ stands for ‘cost is low’…………….(3)

from (1) and (2) sil = home

from (2) and (3) kon = is

thus good = hit

Given,

‘ABC DEF’ is written as ‘ZYX WVU’

To solve this code, first write out the alphabet, and
then write out the alphabet in reverse below it:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Z Y X W V U T S R Q P O N M L K J I H G F E D C B A


∴ ‘LOSS’ can be coded as ‘OLHH’ , as the reverse of ‘L’ is ‘O’,’O’ is ‘L’,’S’ is ‘H’.

‘oka peru’ means ‘fine cloth’, ‘meta lisa’ means ‘clear water’ and ‘dona lisa peru’ means ‘fine clear weather’

from this when we look for the common codes, we get

fine=peru

clear=lisa

weather=dona
