Correct option is B
Given:
Spend on Rent = 50% of Salary.
Remaining = 50% of Salary.
Expenses from remaining: Transport (₹912), Groceries (₹3799).
Savings = ₹131.
Solution:
Calculate the total value of the remaining 50% part.
Since this remaining amount is 50% of the total salary, the total salary is double this amount.
Exam-Hall Method:
Sum the absolute values: 912 + 3799 + 131 = 4842.
Since 50% is gone in rent, this sum represents the other 50%.
Total
So the correct answer is (b)
