Correct answer: B
Answer: Rs 2400
Explanation:
Let Felix’s monthly salary be Rs x.
Interpret 66.66% as two-thirds (66.666...). Then the savings percentage is 100% − 66.666...% = 33.333...% = 1/3 of the salary.
So (1/3) of x = Rs 1200 ⇒ x = Rs 3600.
Monthly expenditure = (2/3) of x = (2/3) × 3600 = Rs 2400.
Algebraic check: x − (2/3)x = (1/3)x = 1200 ⇒ x = 3600, so expenditure = (2/3)x = 2400.
