# Language Application: Given below are few Mathematical terms.

Find the percentage of consonants in each of the terms.

**Solution:**

Given, the figure represents few mathematical terms.

We have to find the percentage of consonants in each of the terms.

We know, Vowels means a, e, i, o, u and consonants are letters apart from vowels.

Percentage of consonants = number of consonants/total letters × 100

(i) Hypotenuse

Total number of words = 10

Number of consonants = 6

Percentage of consonant = 6/10 × 100

= 6 × 10

= 60

Therefore, the required percentage is 60%

(ii) Congruence

Total number of words = 10

Number of consonants = 6

Percentage of consonant = 6/10 × 100

= 6 × 10

= 60

Therefore, the required percentage is 60%

(iii) Perpendicular

Total number of words = 13

Number of consonants = 8

Percentage of consonant = 8/13 × 100

= 800/13

= 61.53

Therefore, the required percentage is 61.53%

(iv) Transversal

Total number of words = 11

Number of consonants = 8

Percentage of consonant = 8/11 × 100

= 800/11

= 72.72

Therefore, the required percentage is 72.72%

(v) Correspondence

Total number of words = 14

Number of consonants = 9

Percentage of consonant = 9/14 × 100

= 900/14

= 64.28

Therefore, the required percentage is 64.28%
