An increase of Rs. 60 in the monthly salary of Madan made it `50%` of the monthly salary of Kamal. What is Mohan’s present monthly salary?

Options

A. Rs. 180
B. Rs. 240
C. Rs. 300
D. Data inadequate

Answer

To solve the problem step-by-step, let's denote:

- Madan's original monthly salary as \( M \).
- Kamal's monthly salary as \( K \).

According to the problem, when Madan's salary is increased by Rs. 60, it becomes 50% of Kamal's salary. We can express this relationship mathematically.

### Step 1: Set up the equation

When Madan's salary increases by Rs. 60, we have:

\[ M + 60 = 0.5K \]

### Step 2: Rearranging the equation

To express Kamal's salary in terms of Madan's salary, we can rearrange the equation:

\[ K = 2(M + 60) \]

### Step 3: Substitute Madan's salary

We don't have any specific information about Mohan's salary or a direct relationship between Madan's and Mohan's salary. Therefore, we cannot determine Mohan's salary based on the information provided.

### Conclusion

Since we have no information about Mohan's salary, we conclude that the data is inadequate to find Mohan's present monthly salary.
