Answer 1

He had 900 in the beginning. 20% of 900 is 180

Answer 2

Concept:

Saving is the amount that is saved after the expenditure from the salary.

Given:

Mohan spends of total salary = 80%

And,

Saving of Mohan = Rs. 180

Find:

We are asked to find the money Mohan had in the beginning.

Solution:

We have,

Mohan spends of total salary = 80%

And,

Saving of Mohan = Rs. 180

So,

Let total salary = y

So,

According to the question,

Mohan spends of total salary = 80%

i.e.

80% of y

And,

Saving of Mohan = Rs. 180

i.e.

y - 80% of y = 180

Now, on solving,

y - (4/5)y = 180

Now,

5y - 4y = 180 × 5

We get,

y = 900

So,

Total Salary = Rs. 900

Hence, the money Mohan had, in the beginning, was Rs. 900.
