44. If CHARGER is coded as 129, then HINGES will be coded as: [RRB NTPC 16/01/2021 (Evening)]

Correct Answer: (b) 100
Solution:

Sum of place values opposite of the letters.
CHARGER
= 24 + 19 + 26 + 9 + 20 + 22 + 9 = 129
HINGES
= 19 + 18 + 13 + 20 + 22 + 8 = 100

45. PI = Y and SD = W, then find GN = ? [RRB NTPC 16/01/2021 (Evening)]

Correct Answer: (d) U
