"Six girls and eight boys"
Translation:छह लड़कियाँ और आठ लड़के
Visarga (ḥ) Translated literally, Visarga means "to send out" or "to release". It creates a softer, lingering sound after the vowel. There are two forms of visarga -guttural and fricative,The former may be pronounced before ⟨क⟩, ⟨ख⟩, and the latter before ⟨प⟩, and ⟨फ⟩. I'm not sure why it would be used before ल, in Hindi.
