RRB ALP 2018 CBT 2 Fitter Question Paper (21-Jan-2019) (Shift 3)
The correct answer is

M

This solution explains the process of rearranging letters in the word ACCUMULATE based on specific interchange rules and finding the 6th letter from the left in the modified word.

Interchanges in the Word ACCUMULATE

The original word given is ACCUMULATE. It has 10 letters. The task involves interchanging pairs of letters based on their positions:

  • The $1^{st}$ letter is swapped with the $2^{nd}$.
  • The $3^{rd}$ letter is swapped with the $4^{th}$.
  • The $5^{th}$ letter is swapped with the $6^{th}$.
  • The $7^{th}$ letter is swapped with the $8^{th}$.
  • The $9^{th}$ letter is swapped with the $10^{th}$.

Let's trace the transformation step-by-step:

Original Word: A C C U M U L A T E

Positions: 1 2 3 4 5 6 7 8 9 10

Applying the interchanges:

  • Swap $1^{st}$ (A) and $2^{nd}$ (C): C A C U M U L A T E
  • Swap $3^{rd}$ (C) and $4^{th}$ (U): C A U C M U L A T E
  • Swap $5^{th}$ (M) and $6^{th}$ (U): C A U C U M L A T E
  • Swap $7^{th}$ (L) and $8^{th}$ (A): C A U C U M A L T E
  • Swap $9^{th}$ (T) and $10^{th}$ (E): C A U C U M A L E T

The resulting word after all interchanges is CAUCUMALET.

To visualize this transformation clearly, here is a table:

Original Position $1^{st}$ $2^{nd}$ $3^{rd}$ $4^{th}$ $5^{th}$ $6^{th}$ $7^{th}$ $8^{th}$ $9^{th}$ $10^{th}$
Original Letter A C C U M U L A T E
Interchanged Letter C A U C U M A L E T
Final Position $1^{st}$ $2^{nd}$ $3^{rd}$ $4^{th}$ $5^{th}$ $6^{th}$ $7^{th}$ $8^{th}$ $9^{th}$ $10^{th}$

Identifying the 6th Letter from Left

The question asks for the 6th letter from the left in the newly formed word.

The modified word is: C A U C U M A L E T

Let's count the letters from the left:

  • $1^{st}$ letter: C
  • $2^{nd}$ letter: A
  • $3^{rd}$ letter: U
  • $4^{th}$ letter: C
  • $5^{th}$ letter: U
  • $6^{th}$ letter: M
  • $7^{th}$ letter: A
  • $8^{th}$ letter: L
  • $9^{th}$ letter: E
  • $10^{th}$ letter: T

The 6th letter from the left is M.
