Richa has milk teeth which fell down when permanent teeth were starting to grow. It may happen that 4 teeth fell down but permanent teeth have not come so it is looking like she has 12. In actual she also has 16 teeth.
Her father already had his permanent teeth grow and they have not fell down due to any accident or something thats why he has 16 teeth.
But the fact is that both Richa and her Father would have 16 teeth.
Pls mark me as the brainliest answer......
