Find the value of x.

\(\frac{2}{5}(x) + \frac{3}{10}(x) - \frac{3}{5}(x) = 459\)

This question was previously asked in
RPF SI 2018 Question Paper PDF (10-Jan-2019) (Shift 1)
The correct answer is

4590

Take LCM 10: \(\frac{4x}{10} + \frac{3x}{10} - \frac{6x}{10} = 459\).

Combine: \(\frac{4x + 3x - 6x}{10} = \frac{x}{10} = 459\).

\(x = 459 \times 10 = 4590\).

Hence, the value of x is 4590.
