Last Updated On: Sat Aug 29 2026Given Data
- In a certain code language, 'DELHI' is written as 38.
Question
How will 'MUMBAI' be coded in that language?
Answer
59.
Solution
- Find forward alphabetical positions of letters in 'DELHI':
- D = 4, E = 5, L = 12, H = 8, I = 9.
- Sum of positions = 4 + 5 + 12 + 8 + 9 = 38.
- The code is the direct sum of the alphabetical ranks of all letters.
- Calculate the sum of letter ranks for 'MUMBAI':
- M = 13, U = 21, M = 13, B = 2, A = 1, I = 9.
- Sum = 13 + 21 + 13 + 2 + 1 + 9 = 59.
- Therefore, 'MUMBAI' is coded as 59.
