Mathematics · Quantity Comparison

Determine the relationship between the three given quantities: Quantity I: Q is a three-digit number where the unit digit is x, the tens digit is y, and the hundredth digit is z. The hundredth digit is larger than the tens digit and smaller than the unit digit. The difference between the unit digit and the tens digit is 3, while the sum of the digits is 17. If the tens digit is a perfect square, find the value of 4x + 2y - 5z. Quantity II: A box contains 4 Red balls, 3 White balls, 5 Orange balls, and 6 Blue balls. If two balls are drawn at random, find the value of (Probability that both balls are either orange or blue) × 50. Quantity III: A shopkeeper purchases a mobile phone for Rs (10q + 500). If he sells it after giving a 10% discount, he earns a 17% profit. If he sells it after giving two successive discounts of 10% and Rs 330, he earns a 15% profit. Find the value of q / 100.
