The present age of Sita's father is three times of Sita's present age. After 6 years the sum their age will be 69. Find their present age

Age of Sita is 14.25 years and her father is 42.75 years

Step-by-step explanation:

Step 1: From given details, let present age of Sita be x and that of her father be 3x. Step 2: Form equations based on their ages in 6 years. (Given sum is 69)

⇒ (x + 6) + (3x + 6) = 69

⇒ 4x + 12 = 69

⇒ 4x = 57

⇒ x = 14.25

Step 3: Calculate age of Sita's father

⇒ 3x = 42.75
