Answer 2

Given:

By increasing the salary of a man by 20% it becomes rupees 18000.

To find:

The original salary of man.

Solution:

The original salary of a man is 15,000 Rs.

We can find the answer by using the following steps:

As given, we have,

When the salary of a man is increased by 20%, it becomes rupees 18000.

So, let the original salary of a man be x Rs.

So, according to the question,

$x + \frac{20}{100} x = 18000$

Now, after multiplying both sides by 100, we get

$100x + 20x = 18000 \times 100$

$120x = 18000 \times 100$

On solving the above, we get,

$x = \frac{18000 \times 100}{120}$

$= \frac{18000 \times 5}{6}$

$= 3000 \times 5$

$= 15000 \: Rs.$

Hence, the original salary is 15,000 Rs.
