Each question involves rearranging specific positions of the letters from the original word, and you must choose the correct transformed version from the options. PLANET is to EAP LNT as TARGET is to:

Correct — C.
Rule: odd-position letters in reverse, then even-position letters in order.

PLANET: odd P, A, E → reversed EAP. Even L, N, T → LNT. That gives EAP LNT.

TARGET: odd T, R, E → reversed ERT. Even A, G, T → AGT.

ERT + AGT = ERTAGT → option (c).

Why the others are wrong

• (a)
  AGETRT — AGETRT starts with A, TARGET's 2nd letter. The rule starts with the 5th letter, as E leads EAP LNT, so the answer begins with E.
• (b)
  GAE TRT — GAE TRT copies the space in EAP LNT but not the order. It starts with G, the 4th letter, where the rule puts the 5th letter, E, first.
• (d)
  GEA TRT — GEA TRT also copies the space and starts with G. Its first block, G, E, A, mixes even and odd positions (4th, 5th, 2nd).

For a letter-rearrangement analogy, number the letters of the first word and write down the position of each letter in the coded word. PLANET → EAP LNT is 5, 3, 1, 2, 4, 6.

Then name the pattern: the odd positions backwards (5, 3, 1), then the even positions forwards (2, 4, 6). Apply the same positions to TARGET, not the same letters.

Key facts

• PLANET → EAP LNT uses positions 5, 3, 1, 2, 4, 6.
• TARGET taken in that order gives E, R, T, A, G, T.
• TARGET has T at both the 1st and the 6th positions.

Common traps

• Choosing an option for its space, like EAP LNT, instead of checking the letter order
• Reversing all six letters instead of the odd-position ones alone
