Question
I. 3x2 - 14x + 15 = 0 II.
15y2 - 34 y + 15 = 0 In the following questions two equations numbered I and II are given. You have to solve both the equations. Give answer if;Solution
I. 3x2 - 14x + 15 = 0 3x2 - 9x - 5x + 15 = 0 3x(x – 3) – 5(x – 3) = 0 (x – 3) (3x – 5) = 0 x = 3 , 5/3 II. 15y² - 34y + 15 = 0 15y² - 25y - 9y + 15 = 0 5y(3y – 5) – 3(3y – 5) = 0 (3y – 5) (5y – 3) y = 5/3 , 3/5 Hence, x ≥ y
784.69 + 86.96 ÷ 29.01 = 40.01 + ? + 367.88
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(44/25) ÷ (154/199.5) × 419.91 = ? – (11.11)3
98.999 x 99.001 + 640.856=?
(79.79% of 800.24 - √224.75) × (2/5 of 499.71) ÷ (10% of 600.26) = ?
6106.11 ÷ √? × 55.9 = 3976.21 Â
811.85 ÷ 28.05 + 462.16 – 23.06 × 17.95 = ?
(√8648 ×7) ÷ (3.9 ×5.99) = ?
?% of 1200.22 + 319.82 = 3.99 × 295.64
60.22 of 349.98% + 419.99 ÷ 14.18 = ?
