Here' the answer to the question. please write back in case you've doubts.

Here below, we code the statement logic in R programming software:

The following R scripts asks her Score ( here declared 100) and then assigns a letter code grade in the variable "Grade".

# declare your score here.
Score <- 100

if ( Score > 90) {
Grade <- 'A'
} else if ( Score > 80 & Score <= 90) {
Grade <- 'B'
} else if ( Score > 70 & Score <= 80) {
Grade <- 'C'
} else if ( Score > 60 & Score <= 70) {
Grade <- 'D'
} else if ( Score < 60 ) {
Grade <- 'Failed the Test'
}
