Shweta spends 21% of her monthly salary on house rent, 14% on education, and 13% on entertainment, and still saves ₹5,408. What is her monthly salary (in ₹)?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 10,400.
Let the monthly salary be ₹x.
House rent expenditure = 0.21x
Education expenditure = 0.14x
Entertainment expenditure = 0.13x
Total monthly salary = 0.21x + 0.14x + 0.13x + 5408
⇒ x = 0.21x + 0.14x + 0.13x + 5408
⇒ x = 0.48x + 5408
⇒ x - 0.48x = 5408
⇒ 0.52x = 5408
⇒ x = 5408 / 0.52
⇒ x = 10400
