Layla" is a song written by Eric Clapton and Jim Gordon, originally recorded by Derek and the Dominos, as the thirteenth track from their only studio album, Layla and Other Assorted Love Songs (1970).
What i understand from the statement given is that the expression will be: 10m + n/4 where m = 5 and n = 16 now by putting the values of m and n in the expression,we get 10(5) + 16/4 =50 + 4 = 54 Thus, after solving the expression we get the answer 54.
