UPSC Prelims 2019 CSAT Paper II · Q68 of 79 Logical Reasoning medium

If every alternative letter of the English alphabet from B onwards (including B) is written in lower case (small letters) and the remaining letters are capitalized, then how is the first month of the second half of the year written ?

  1. (a) JuLY
  2. (b) jULy
  3. (c) jUly
  4. (d) jUlY ✓ UPSC's answer

Why the answer is (d)

• The first month of the second half of the year is July.

• The rule states that every alternative letter from B onwards (B, D, F, H, J, L, N, P, R, T, V, X, Z) is written in lowercase.

• The remaining letters (A, C, E, G, I, K, M, O, Q, S, U, W, Y) are capitalized.

• Applying this to 'July': J is in the lowercase set (B, D, F, H, J...), so it becomes 'j'.

• U is in the capitalized set (A, C, E, G, I, K, M, O, Q, S, U...), so it remains 'U'.

• L is in the lowercase set (B, D, F, H, J, L...), so it becomes 'l'.

• Y is in the capitalized set (A, C, E, G, I, K, M, O, Q, S, U, W, Y), so it remains 'Y'.

• The resulting string is 'jUlY', which corresponds to option (d).

Why the other options are wrong

(a) JuLY
Option (a) incorrectly capitalizes J and L, which are in the alternative lowercase sequence starting from B.
(b) jULy
Option (b) incorrectly capitalizes L, which is in the alternative lowercase sequence starting from B.
(c) jUly
Option (c) incorrectly capitalizes L, which is in the alternative lowercase sequence starting from B.
