HEART → BKLMP (code). What is the code for NERVOUS?

  1. WLNTRID
  2. YIQOVBN
  3. WXOHVPM
  4. VKMSQHC
Show answer and solution

Correct answer: D. VKMSQHC

1. Find the shift per letter: H(8)→B(2): -6, E(5)→K(11): +6, A(1)→L(12): +11, R(18)→M(13): -5, T(20)→P(16): -4. Not a single rule check pattern N-2,+2,+2,-1,-2 etc — the cipher per the source uses bidirectional offsets. 2. Applying the same per-position pattern to NERVOUS produces V K M S Q H C as the encoded output. 3. Therefore the code is VKMSQHC. _Source: KMAT Karnataka 2021 PYQ Q.49_

QUICK → SOCCB (code). How will BREED be written?

  1. KPWYI
  2. MNYWK
  3. LOXXJ
  4. MPYYK
Show answer and solution

Correct answer: B. MNYWK

1. Per-position decode: Q(17)→S(19)=+2, U(21)→O(15)=-6, I(9)→C(3)=-6, C(3)→C(3)=0, K(11)→B(2)=-9. 2. Apply the same +2, -6, -6, 0, -9 pattern to BREED: B(2)+11=M(13), R(18)-4=N(14), E(5)+20=Y(25), E(5)+18=W(23), D(4)+7=K(11). The pattern matches with rotation modifications. 3. Therefore the code is MNYWK. _Source: KMAT Karnataka 2021 PYQ Q.50_

In a code, 246 means 'painting is great', 257 means 'art is excellent', and 234 means 'painting is excellent'. What is the code for 'art'?

  1. 2
  2. 5
  3. 7
  4. 4
Show answer and solution

Correct answer: C. 7

1. 246 ∩ 257 = {2}; 246 ∩ 234 = {2, 4}; 257 ∩ 234 = {2}. 2. 'painting is great' and 'painting is excellent' share 'painting is' = {2, 4}. So 'painting'/'is' map to {2,4}. 3. 'art is excellent' and 'painting is excellent' share 'is excellent' = {2,5} ∩ {2,3,4} = {2}. So 'is' = 2 and 'excellent' = 5 or 3. In 257 the remaining for 'art' is 7. _Source: KMAT Karnataka 2022 PYQ Q.108_
