In a certain code “SOUTH” is coded as “95208”, “OLD” is coded as “524”, then how is the word “LAST” is coded ?Options311022190None12119203112

The word "LAST" is coded as "1902".

Here's how we get to that:

1. Each letter in the word is replaced by a number. The number corresponds to the position of the letter in the alphabet.

2. For the word "SOUTH", S is the 19th letter of the alphabet, O is the 15th, U is the 21st, T is the 20th, and H is the 8th. So, "SOUTH" is coded as "19201521208".

3. Similarly, for the word "OLD", O is the 15th letter of the alphabet, L is the 12th, and D is the 4th. So, "OLD" is coded as "151204".

4. Using the same logic, the word "LAST" would be coded as "1902". L is the 12th letter of the alphabet, A is the 1st, S is the 19th, and T is the 20th. So, "LAST" is coded as "1211920".

5. However, in the given code, the 0s are removed. So, "LAST" is coded as "1902".

Therefore, the correct option is 1902.
