UPSC Prelims 2018 CSAT Paper II · Q22 of 58 Logical Reasoning easy

If RAMON is written as 12345 and DINESH as 675849, then HAMAM will be written as

  1. (a) 92233
  2. (b) 92323 ✓ UPSC's answer
  3. (c) 93322
  4. (d) 93232

Why the answer is (b)

• From RAMON = 12345, the letter mapping is R=1, A=2, M=3, O=4, N=5.

• From DINESH = 675849, the letter mapping is D=6, I=7, N=5, E=8, S=4, H=9.

• Combining these, the specific values for the letters in HAMAM are H=9, A=2, M=3.

• Substituting these values into HAMAM gives H(9) A(2) M(3) A(2) M(3).

• The resulting sequence is 92323, which corresponds to option (b).

Why the other options are wrong

(a) 92233
Option (a) 92233 incorrectly assigns the value 2 to the letter M instead of 3.
(c) 93322
Option (c) 93322 incorrectly assigns the value 3 to the letter A instead of 2.
(d) 93232
Option (d) 93232 incorrectly assigns the value 3 to the letter A instead of 2.
