If A = 4, K = 3, N = 2, P = 1, then the sum of which set of the letters makes the highest number?
Discuss
Answer & Solution
Answer: Option D
Solution:

Given, A = 4, K = 3, N = 2, P = 1.
Sum of first Set,
= K + A + N + P +K = 3 + 4 + 2 + 1 + 3 = 13.
Sum of the second set,
N + P + A + K +N = 2 + 1 + 4 + 3 + 2 = 12.
Sum of the third set,
P + K + A + N + A = 1 + 3 + 4 + 2 + 3 = 13.
Sum of the fourth set,
N + A + K + N + A = 2 + 4 + 3 + 2 + 4 = 15.

In a certain code ORCHESTRA is written as ARTSEORCH. How is DREAMLAND written in that code. ORESTRA
Discuss
Answer & Solution
Answer: Option C
Solution:
Look at the given example: ORCHESTRA → ARTSEORCH.

Compare letters by position (original → code):

O R C H E S T R A → A R T S E O R C H

So the code takes the part after the first four letters (that is, from the 5th letter to the end), reverses that part, and then appends the first four letters unchanged.

In other words: code = reverse(original[5..end]) + original[1..4].

Apply this rule to DREAMLAND:

First four letters = DREA

Remaining part = MLAND

Reverse the remaining part: DNALM

Append the first four letters: DNALM + DREA = DNALMDREA

Thus the coded form of DREAMLAND is DNALMDREA (Option C).
