Quantity I. let the larger number be x ∴ Smaller number = (x-21) ∴ x(x – 21) = 70 × 7 x2 - 21x = 490 x2 - 21x – 490 = 0 (x-35)(x+14) = 0 ∴ x = 35 Larger number = 35 and Smaller number = 14 Quantity II. Let the larger number be x ∴ Smaller number = 60 – x ∴ x (60-x) = 12 ×72 x2 - 60x + 864 = 0 (x-36)(x-24) = 0 ∴ x = 36, 24 Larger number = 36 Smaller number = 24 Hence, Quantity I < Quantity II.
