Question
Equation 1: x² - 200x + 9600 = 0 Equation 2: y²
- 190y + 9025 = 0Solution
From Equation 1: x² - 200x + 9600 = 0 Factorizing: (x - 120)(x - 80) = 0 So, x = 120 or x = 80. From Equation 2: y² - 190y + 9025 = 0 Factorizing: (y - 95)(y - 95) = 0 So, y = 95 (repeated root). Comparing x and y: x = 120, y = 95 → x > y x = 80, y = 95 → x < y Correct option: E) x = y or no relation
(630 ÷ 18 + 24 of 25) ÷ 5 = ?
(18 × 9 ÷ 6) × 3 = ?
√225 + 27 × 10 + ? = 320
Simplify the expression:
(9x² - 25) / (3x + 5)
(18 x 3) + (36 x 8) = ? + 10
16 × 14 + 30 × 21 = 14 × ?
125 + 30% of 250 + √576 = ?
What will come in the place of question mark (?) in the given expression?
(308 – 154) ÷ 11 = ? ÷ 15
(-251 × 21 × -12) ÷ ? = 158.13
