Question : Directions: Select the option that is related to the fifth letter cluster in the same way as the second letter cluster is related to the first letter cluster and the fourth letter cluster is related to the third letter cluster. ORANGE : FIQEWU :: MANGO : PIQER :: APPLE : ?
Option 1: ELPPA
Option 2: FNSTF
Option 3: GNSTG

Thus, MANGO is coded as PIQER. Similarly, follow the same pattern for APPLE –
So, FNSTF is coded as APPLE. Hence, the second option is correct.
Question : If $m$ and $n$ are two positive real numbers such that $9 m^2+n^2=40$ and $mn = 4$, then the value of $3m + n$ is:
Option 1: 160
Option 2: 64
Option 3: 10
Option 4: 8
Correct Answer: 8
Solution : Given, $9 m^2+n^2=40$ and $mn = 4$ So, $9 m^2+n^2+6mn=40+6(4)$ ⇒ $ (3m+n)^2=64$ ⇒ $3m+n=8$ Hence, the correct answer is 8.

Question : Directions: In a certain code language, BENT is coded as 3198 and DEBT is coded as 8316. What is the code for N in the given code language?
Option 1: 1
Option 2: 9
Option 3: 3
Correct Answer: 9
Solution : Given: BENT is coded as 3198, and DEBT is coded as 8316.
Compare both the given words, BENT, and DEBT. In both the words, (B, E, T) are the common letters, and in their codes (1, 3, 8) are the common digits. So, in the word BENT, N is the remaining letter and in its code 9 is the remaining digit. Similarly, in the word DEBT, D is the remaining letter and in its code 6 is the remaining digit.
So, N is coded as 9. Hence, the second option is correct.
