Using some code, BEAT has been written as GIDV. Discover this code and use it to write SOUP in the code language.

    Answer:

    Let us see if there is some pattern in the code used. We write the letter of the English alphabet around a circle as shown below. Now     \[B\to G\]                     \[E\to I\]             \[A\to D\]                     \[T\to V\] From fig. you can see that there are 4 letters between B and \[\text{G}:3\]letters between E and 1:2 letters between A and D and only one letter between T and V. Using the same pattern \[S\to X\]                      \[O\to S\] \[U\to X\]         \[P\to R\] Hence in the above code, SOUP will be written as XSXR.
