Question

man deposit 10% of his salary an PF. He saves 30% of the remaining. The ratio of his expense on medicine & groceries is 3:4 of the remaining salary after saving. If his expense on medicine RS 2700. Fird his monthly salary.​

Answer 1

Answer:

His monthly salary is Rs. 10,000.

Step-by-step explanation:

Let's assume that the man's monthly salary is Rs. x.

∴ He deposit 10% = 10x/100 = 0.1x in PF

∴ His remaining salary = (1 - 0.1)x = 0.9x

∴ He saves 30% of 0.9x = (30 . 0.9x)/100 = 0.27x

∴ His remaining salary after saving = (0.9 - 0.27)x = 0.63x

His medicine expenses $=\frac{3}{3+4}$ times 0.63x = 0.27x

His groceries expenses $=\frac{4}{3+4}$ times 0.63x = 0.36x

According to the problem:

0.27x = 2700

∴ x = 10,000
