Letter and Symbol Series Aptitude MCQ Questions with Answers Set 02

Answer: (d) flt

Explanation:
1. In the pyramid, c-g-m runs straight down the middle column and m-n-o then runs to the right from m, forming an L shape.
2. tuv lies on the fifth row, so the missing group must run straight down and end at t.
3. f, l and t lie one below the other in the column just left of the centre, and the line ends at t; then t-u-v turns right, completing the same L.
4. Hence the answer is flt.

Teacher's Note:
1. Copy the pyramid on rough paper and trace each letter group with your pencil; the shape it makes (line, L, cross, V) is the real relationship.
2. Check direction as well as shape: a mirror-image or reversed path usually separates the correct option from the distractors.

Answer: (c) nop

Explanation:
1. g-m-u is a vertical line in the centre column and l-m-n is a horizontal line whose middle letter is m.
2. So the two groups cross at their middle letters, forming a plus (+) shape.
3. i-o-w is a vertical line with middle letter o; the horizontal line with o in the middle is n-o-p.
4. Hence the answer is nop.

1. Copy the pyramid on rough paper and trace each letter group with your pencil; the shape it makes (line, L, cross, V) is the real relationship.
2. Check direction as well as shape: a mirror-image or reversed path usually separates the correct option from the distractors.

Answer: (b) tlf

Explanation:
1. x-w-v runs left along the fifth row and ends at v; v-n-h then runs straight up from v. The two lines form an L.
2. r-s-t runs along the fifth row and ends at t.
3. Going straight up from t gives t, l, f.
4. Hence the answer is tlf.

2. Check direction as well as shape: a mirror-image or reversed path usually separates the correct option from the distractors.

Answer: (b) ORUX

Explanation:
1. Each letter of BEGK moves one step back: B-1 = A, E-1 = D, G-1 = F, K-1 = J, giving ADFJ.
2. Apply the same rule to PSVY: P-1 = O, S-1 = R, V-1 = U, Y-1 = X.
3. Hence the answer is ORUX.

Teacher's Note:
1. Write each letter's position number (A = 1 ... Z = 26) under it; letter analogies become simple number patterns.
2. Apply the rule letter by letter and in the same order; one wrong position is the usual trap in such options.

Answer: (a) GTHS

Explanation:
1. In AZBY to CXDW, the 1st and 3rd letters move 2 steps forward (A to C, B to D) and the 2nd and 4th move 2 steps back (Z to X, Y to W).
2. For EVFU: E+2 = G, V-2 = T, F+2 = H, U-2 = S.
3. Hence the answer is GTHS.

Teacher's Note:
1. Write each letter's position number (A = 1 ... Z = 26) under it; letter analogies become simple number patterns.
2. Apply the rule letter by letter and in the same order; one wrong position is the usual trap in such options.

Answer: (d) P, N

Explanation:
1. Positions: Z = 26, X = 24, V = 22, T = 20, R = 18.
2. Each letter is 2 places before the previous one (one letter skipped, in reverse order).
3. Next: 18 - 2 = 16 (P) and 16 - 2 = 14 (N).

Teacher's Note:
1. Convert letters to their positions (use EJOTY: E = 5, J = 10, O = 15, T = 20, Y = 25) and look at the differences.
2. When each term has two or more letters, track each letter position as a separate series.

Answer: (d) OE

Explanation:
1. First letters: N(14), I(9), D(4), Y(25), T(20) - each is 5 places back, wrapping from A to Z. Next: 20 - 5 = 15 = O.
2. Second letters: D(4), Y(25), T(20), O(15), J(10) - also 5 places back each time. Next: 10 - 5 = 5 = E.
3. So the missing term is OE.

Teacher's Note:
1. Convert letters to their positions (use EJOTY: E = 5, J = 10, O = 15, T = 20, Y = 25) and look at the differences.
2. When each term has two or more letters, track each letter position as a separate series.

Answer: (d) XW

Explanation:
1. First letters: J(10), L(12), O(15), S(19) - gaps +2, +3, +4, so next is +5: 24 = X.
2. Second letters: E(5), H(8), L(12), Q(17) - gaps +3, +4, +5, so next is +6: 23 = W.
3. So the missing term is XW.

Teacher's Note:
1. Convert letters to their positions (use EJOTY: E = 5, J = 10, O = 15, T = 20, Y = 25) and look at the differences.
2. When each term has two or more letters, track each letter position as a separate series.

Answer: (c) EJO

Explanation:
1. First letters B, C, D move +1: next E.
2. Second letters D, F, H move +2: next J.
3. Third letters F, I, L move +3: next O.
4. So the missing term is EJO.

Teacher's Note:
1. Convert letters to their positions (use EJOTY: E = 5, J = 10, O = 15, T = 20, Y = 25) and look at the differences.
2. When each term has two or more letters, track each letter position as a separate series.

Answer: (d) MNOP

Explanation:
1. Each term has one more letter than the one before, written in alphabetical order, so the missing term has 4 letters.
2. First letters: A(1), C(3), G(7), ?, U(21) - gaps +2, +4, +6, +8, so the missing term starts at 7 + 6 = 13 = M.
3. So the missing term is MNOP.

Teacher's Note:
1. Convert letters to their positions (use EJOTY: E = 5, J = 10, O = 15, T = 20, Y = 25) and look at the differences.
2. When each term has two or more letters, track each letter position as a separate series.

Answer: (b) IJPO

Explanation:
1. The first pair moves forward 4 places each time: AB, EF, IJ, MN.
2. The last pair moves back 4 places each time: XW, TS, PO, LK.
3. So the missing group is IJPO.

Teacher's Note:
1. Split each group into its 1st, 2nd, 3rd ... letters and study each column on its own.
2. Letters that stay the same in every group are fixed; concentrate only on the ones that change.

Answer: (a) NHR

Explanation:
1. First letters B, E, H, K move +3: next N.
2. Second letters X, T, P, L move -4: next H.
3. Third letters J, L, N, P move +2: next R.
4. So the answer is NHR.

1. Split each group into its 1st, 2nd, 3rd ... letters and study each column on its own.
2. Letters that stay the same in every group are fixed; concentrate only on the ones that change.

Answer: (c) ISS

Explanation:
1. First letters C, E, G, ?, K move +2, so the missing one is I.
2. The repeated letters M, O, Q, ?, U also move +2, so the missing pair is SS.
3. So the answer is ISS.

1. Split each group into its 1st, 2nd, 3rd ... letters and study each column on its own.
2. Letters that stay the same in every group are fixed; concentrate only on the ones that change.

Answer: (a) HGF

Explanation:
1. Reading the whole series letter by letter gives Q P O N M L K J I ... E D C - the alphabet backwards.
2. The letters between I and E are H, G, F.
3. So the missing group is HGF.

1. Split each group into its 1st, 2nd, 3rd ... letters and study each column on its own.
2. Letters that stay the same in every group are fixed; concentrate only on the ones that change.

Answer: (b) NEO

Explanation:
1. Middle letters run A, B, C, D, E.
2. First letters run J, K, L, M, N and the third letter is always one after the first.
3. So the next group is NEO.

1. Split each group into its 1st, 2nd, 3rd ... letters and study each column on its own.
2. Letters that stay the same in every group are fixed; concentrate only on the ones that change.

Answer: (a) JKJ

Explanation:
1. The first two letters of each group follow on: BC, DE, FG, HI, JK.
2. The third letter repeats the first.
3. So the next group is JKJ.

Teacher's Note:
1. Split each group into its 1st, 2nd, 3rd ... letters and study each column on its own.
2. Letters that stay the same in every group are fixed; concentrate only on the ones that change.

Answer: (a) UAV

Explanation:
1. The middle letter A is fixed.
2. The last letter of each group becomes the first letter of the next: R, S, T, U.
3. So the next group starts with U and ends with V: UAV.
