Here are some words translated from an artificial language.
dionot means oak tree
blyonot means oak leaf
blycrin means maple leaf
Which word could mean “maple syrup”?

Answer: Option C


In this language, the adjective follows the noun. From dionot and blyonot, you can determine that ‘onot’ means oak. From blyonot and blycrin, you can determine that bly means leaf. Therefore, crin means maple. Because the adjective maple comes after the noun, patricrin is the only possible choice.

Answer: Option C


In the second and third statements, the common code is ‘9a’ and the common word is ‘not’. So, ‘9a’ means ‘not’. In the first and second statements, the common codes are ‘7c’ and ‘3a’ and the common words are ‘is’ and ‘Eternal’. So, in the second statements, ‘8b’ means ‘enmity’.

If in code of alphabet AT = 20, BAT = 40 then CAT = ?

Answer: Option D


By considering A=1 B=2 ………… T=20 …….. Z = 26
We can say that
A × T = 1 × 20 = 20
B × A × T = 2 × 1 × 20 = 40
C × A × T = 3 × 1 × 20 = 60
