PIEAS Entry Test intelligence: Coding & Decoding MCQs — sample questions

1. Question 1

   Q1. In a certain code, 'DEEP' is coded as '8 5 5 16'. How will 'RICE' be coded?

   • A) 18 9 3 5
   • B) 9 18 3 5
   • C) 18 3 9 5
   • D) 9 3 18 5

   Answer: 18 9 3 5

   Explanation: The coding is based on the alphabetical position of the letters, where A=1, B=2, ..., Z=26. So, R=18, I=9, C=3, E=5.

2. Question 2

   Q2. If 'TABLE' is coded as '20 1 2 12 5', how will 'CHAIR' be coded?

   • A) 3 8 1 9 18
   • B) 8 3 1 9 18
   • C) 3 8 1 18 9
   • D) 8 3 1 18 9

   Answer: 3 8 1 9 18

   Explanation: The coding is based on the alphabetical position of the letters, where A=1, B=2, ..., Z=26. So, C=3, H=8, A=1, I=9, R=18.

3. Question 3

   Q3. In a certain code, 'GOOD' is written as 'HPRD'. How will 'BAD' be written?

   • A) CBE
   • B) ECB
   • C) CEB
   • D) BCE

   Answer: CEB

   Explanation: The coding is based on incrementing each letter by 1 position, so B+1=C, A+1=B, D+1=E.

4. Question 4

   Q4. If 'COLD' is coded as 'DPME', how will 'FROST' be coded?

   • A) GSPUT
   • B) GPSUT
   • C) GSPUT (2)
   • D) GPUTS

   Answer: GSPUT (2)

   Explanation: The coding is based on incrementing each letter by 1 position, so F+1=G, R+1=S, O+1=P, S+1=T, T+1=U.

5. Question 5

   Q5. In a certain code, '123' means 'hot filtered coffee'. What is the code for 'hot'?

   • A) 1
   • B) 2
   • C) 3
   • D) None of these
