(a) (i) Number of consonants in Hypotenuse $$= 6$$
Number of vowels in Hypotenuse $$= 4$$
Hence, required ratio $$= \dfrac{6}{4} = \dfrac{3}{2} \,i.e. 3 : 2$$
(ii) Number of consonants in Congruence $$= 6$$
Number of vowels in Congruence $$= 4$$
Hence, required ratio $$= \dfrac{6}{4} = \dfrac{3}{2} \,i.e. \,3 : 2$$
(iii) Number of consonants in Perpendicular $$= 8$$
Number of vowels in Perpendicular $$= 5$$
Hence, required ratio $$= \dfrac{8}{5} \,i.e. \,8 : 5$$
(iv) Number of consonants in Transversal $$= 8$$
Number of vowels in Transversal $$= 3$$
Hence, required ratio $$ = \dfrac{8}{3} \,i.e. \,8 : 3$$
(v) Number of consonants in Correspondence $$= 9$$
Number of vowels in Correspondence $$= 5$$
Hence, required ratio $$= \dfrac{9}{5} \,i.e. \,9 : 5$$
(b) (i) Percentage of consonants in Hypotenuse
$$= \dfrac{6}{10} \times 100 = 60\%$$
(ii) Percentage of consonants in Congruence
$$= \dfrac{6}{10} \times 100 = 60\%$$
(iii) Percentage of consonants in Perpendicular
$$=\dfrac{8}{13} \times 100 = 61.53\%$$
(iv) Percentage of consonants in Transversal
$$= \dfrac{8}{11} \times 100 = 72.72\%$$
(v) Percentage of consonants in Correspondence
$$= \dfrac{9}{14} \times 100 = 64.28\%$$
