Ramesh spends 40% of his monthly salary on food, 18% on house rent, 12% on entertainment, and 5% on conveyance. But due to a family function, he has to borrow Rs. 16,000 from a money lender to meet the expenses of Rs. 20,000. His monthly salary is:

A. Rs. 18,000

B. Rs. 16,500

C. Rs. 16,000

D. Rs. 15,000

Answer: Option C

Solution(By Examveda Team)

Let monthly salary = 100x
Total expenditure = (40 + 18 + 12 + 5)x = 75x
25x = 20,000 - 16,000
x $$ = \frac{{4000}}{{25}} = 160$$
Hence monthly salary = 100x = 100 × 160 = 16,000
