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
