Question : Directions: In a certain code language, COSTLY is written as 3P19U12Z. How will EXTEND be written in that language?
Option 1: 5Y20F14E
Option 2: 5Y20G14E
Option 3: 5Y30F14E
Option 4: 5X20F14E
Correct Answer: 5Y20F14E
Solution :
Given:
COSTLY is written as 3P19U12Z.
Write the position values of the letters of COSTLY and add 1 to the position values of the alternate letters to obtain the required code –
C→3; O→15; S→19; T→20; L→12; Y→25
Now, add 1 to the position values of alternate letters –
C→3; O + 1 = P; S→19; T + 1 = U; L→12; Y + 1 = Z
Thus, COSTLY is coded as 3P19U12Z.
Similarly, follow the same pattern for EXTEND –
E→5; X→24; T→20; E→5; N→14; D→4
Now, add 1 to the position values of the remaining letters –
E→5; X + 1 = Y; T→20; E + 1 = F; N→14; D + 1 = E
So, EXTEND is coded as 5Y20F14E. Hence, the first option is correct.
