Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Rs 4,000.
Calculations:
Let the income of Teena and Sheena be 2x and 3x and their expenditures be 3y and 5y.
As we know that
Savings = Income - Expenditures
According to the question;
For Teena:
⇒ 2x - 3y = 1000 ---- (1)
For Sheena:

Solving both equations we get;
⇒ x = 2000 and y = 1000
Income of Teena = 2x = Rs 4000
