Understanding Sita's Age
- Sita's current age is represented as "y" years.
- Her brother's age is twice her age, which can be expressed as "2y" years.
Calculating Brother's Age 2 Years Ago
- To find out how old her brother was 2 years ago, we need to subtract 2 from his current age.
Current Age of Brother
- Current age of Sita's brother = 2y years
Age Calculation
- Brother's age 2 years ago = Current age - 2
- So, it will be: 2y - 2
Final Answer
- Thus, Sita's brother was "2y - 2" years old two years ago.
- This matches option 'b'.

Sita's current age = y years.
Her brother's current age = 2y (since he is twice as old as her).
Her brother's current age = 2y (since he is twice as old as her).
Two years ago, her brother's age = 2y−2
Subtracting 2 from 2y:
2y−2−2 = 2y−4
2y−2−2 = 2y−4
