₹25,275

Gift Article Price Ratio Problem

Let the prices of the three gift articles be \(2x\), \(5x\), and \(8x\), according to the given ratio 2 : 5 : 8.

Calculating the Price Multiplier

  • The difference between the prices of the second and third articles is given as ₹5,055.
  • In terms of the ratio multiplier \(x\), this difference is \(8x - 5x\).
  • Set up the equation: \(8x - 5x = 5055\)
  • Simplify the equation: \(3x = 5055\)
  • Solve for \(x\): \(x = \frac{5055}{3}\) \(x = 1685\)

Finding the Sum of Prices

  • The sum of the prices of the three articles is \(2x + 5x + 8x\).
  • Combine the terms: \(Sum = (2 + 5 + 8)x\) \(Sum = 15x\)
  • Substitute the value of \(x\) found earlier (\(x=1685\)): \(Sum = 15 \times 1685\)
  • Calculate the final sum: \(Sum = 25275\)

Therefore, the sum of the prices of the three gift articles is ₹25,275.
