Question

The words OPEN and SIN are coded, but someone mixed their codes. From which of the following codes, the complete codes for these two words will be formed?

• A. $\left[0\right]\left[5\right]\left[15\right]\left[5\right]\left[0\right]\left[5\right]\left[10\right]$
• B. $\left[0\right]\left[5\right]\left[5\right]\left[5\right]\left[0\right]\left[5\right]\left[10\right]$
• C. $\left[0\right]\left[5\right]\left[5\right]\left[5\right]\left[5\right]\left[5\right]\left[10\right]$
• D. $\left[10\right]\left[5\right]\left[5\right]\left[5\right]\left[0\right]\left[5\right]\left[10\right]$
• E. None of these

Answer 1

Answer: (B)

$\left[0\right]\left[5\right]\left[5\right]\left[5\right]\left[0\right]\left[5\right]\left[10\right]$

1. See $MEET$ and $COOK$ both have codes -$\left[5\right]\left[15\right]\left[15\right]\left[5\right]$. These words are such that their second and third letters have same vowels.
   
2. See $UNIT$ and $OLAP$ both have codes -$\left[0\right]\left[5\right]\left[0\right]\left[5\right]$. These words are such that their first and third letter are vowels.
   
3. See $NEAT$ and $PAIN$ both have codes- $\left[5\right]\left[20\right]\left[20\right]\left[5\right]$.These words are such that second and letter are vowels but different vowels.
   
4. See $TALE$ and $POLE$ both have codes - $\left[5\right]\left[30\right]\left[5\right]\left[30\right]$. These words are such that their seconf and last alphabet are vowels but different vowels
5. See $ATE$ and $ONE$ both have 2 vowels and code is $\left[25\right]\left[5\right]\left[25\right]$
   
6. See $SET$ and $PUT$ both have 1 vowel and code is $\left[5\right]\left[10\right]\left[5\right]$.

$OPEN$ will follow rule 2- and code will be $\left[0\right]\left[5\right]\left[0\right]\left[5\right]$

$SIN$ will follow rule 6- and code will be $\left[5\right]\left[10\right]\left[5\right]$.

So answer will be (B).
