Solution
In mathematical term “Correspondence”,
Number of consonants = 9
Number of vowels = 5 (already calculated)
Total number of letters = Number of consonants + Number of vowels
= 9 + 5
= 14
Percentage of consonants = `"Numerical of consonants"/"Total number of letters" xx 100%`
= `9/14 xx 100%`
= 64.28%
Hence, percentage of consonants is 64.28%.
