Given that,
Vatshala's age = 5 years
Tushar's age = 3(Vatshala's age) + 5
Tushar's age = 3 × 5 + 5 = 15 + 5
Tushar's age = 20 years.
Khushi is two years younger to Tushar.
Khushi's age = (Tushar's age) - 2
Khushi's age = 20 - 2 = 18 years.
Also, Khushi is three years older than Pihoo.
Khushi's age = (Pihoo's age) + 3
Pihoo's age = Khushi's age - 3
Pihoo's age = 18 - 3
Pihoo's age = 15 years.
Hence, the correct answer is "15 years".
