Question

The monthly salaries of three employees A, B and C are in the ratio 3:4:5. If the total monthly salary is Rs.7200, then the salaries of A, B and C are respectively

• A. Rs.2400, Rs.2800 and Rs.3200
• B. Rs.1800, Rs.2400 and Rs.3000
• C. Rs.1600, Rs.2400 and Rs.3200
• D. Rs.1800, Rs.2200 and Rs.3000

Hint:

Add ratio parts first, then divide the total to get the unit value.

Answer 1

The Correct Option is B

To solve the problem of finding the individual salaries of employees A, B, and C, we can use the concept of ratios.

The ratio of their salaries is given as 3:4:5. Let the salaries of A, B, and C be 3x, 4x, and 5x respectively.

The total salary of A, B, and C is Rs. 7200. We can express this as:

\(3x + 4x + 5x = 7200\)

Simplifying the expression, we have:

\(12x = 7200\)

To find the value of x, divide both sides of the equation by 12:

\(x = \frac{7200}{12}\)

Calculating the above division, we get:

\(x = 600\)

Now, we can find the individual salaries:

• Salary of A: \(3x = 3 \times 600 = 1800\)
• Salary of B: \(4x = 4 \times 600 = 2400\)
• Salary of C: \(5x = 5 \times 600 = 3000\)

Thus, the salaries of A, B, and C are Rs. 1800, Rs. 2400, and Rs. 3000 respectively.

Therefore, the correct answer is Rs. 1800, Rs. 2400, and Rs. 3000, which matches the given option: Rs. 1800, Rs. 2400, and Rs. 3000.
