Question
√69.89 + √196.40 + 72.18% of (395.61 + 14.87% of
105.72) = ? 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.)Solution
ATQ;
√69.89 + √196.40 + 72.18% of (395.61 + 14.87% of 105.72) = ?
√70 + √196 + 72% of (396 + 15% of 106) ~ ?
8 + 14 + 72% of (396 + 16) ~ ?
? ~ 22 + 72% of 412
? ~ 22 + 296
? ~ 318
What will be the product of smaller roots of both equations.
I. 27x² + 120x + 77 = 0
II. 56y² + 117y + 36 = 0
I. 18p²- 21p + 6 = 0
II. 16q² - 24q +9 = 0
I. 5x² -14x + 8 = 0
II. 2y² + 17y + 36 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 20x + 96 = 0
Equation 2: y² - 18y + 72 = 0
I.8(x+3) + 8(-x) =72
II. 5(y + 5) + 5(-y) = 150
I. 15/(√x)+9/(√x)=11√x
II. (√y)/4 + (5√y)/12 = 1/(√y)
I. 35 y² + 58 y + 24 = 0
II. 21 x² + 37 x + 12 = 0
(i) 2x² – 12x + 16 = 0
(ii) 2y² – 20y + 48 = 0
I.√(3x-17)+ x=15
II. y + 135/y=24
