Question
In a certain code language, SAFETY is written as 21 –
3 – 8 – 7 – 22 – 27. How will FRIEND be written in that code language?Solution
Positional value of S = 19 + 2 = 21 Positional value of A = 1 + 2 = 3 Positional value of F = 6 + 2 = 8 Positional value of E = 5 + 2 = 7 Positional value of T = 20 + 2 = 22 Positional value of Y = 25 + 2 = 27 Similarly, Positional value of F = 6 + 2 = 8 Positional value of R = 18 + 2 = 20 Positional value of I = 9 + 2 = 11 Positional value of E = 5 + 2 = 7 Positional value of N = 14 + 2 = 16 Positional value of D = 4 + 2 = 6
