Question
1025.08 + 1623.13 - 1784.91 + 2564.31 - 2897.98 =
? 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
1025.08 + 1623.13 – 1784.91 + 2564.31 – 2897.98 = ? 1025 + 1623 – 1785 + 2564 – 2898 ~ ? 5212 – 4683 ~ ? 529 ~ ?
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 54x + 704 = 0
Equation 2: y² - 44y + 448 = 0
How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.
If x^2 - 7x + k = 0 has roots that are equal, what is the value of k?
I. x2 + x – 42 = 0
II. y2 + 6y – 27 = 0
l). 3p + 2q = 27
ll). 4p - 3q = 2
I. 6x² - 23x + 7 = 0
II. 6y² - 29y + 9 = 0
Equation 1: x² - 180x + 8100 = 0
Equation 2: y² - 170y + 7225 = 0
I. 165x² + 97x + 10 = 0
II. 117y² - 163y + 56 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
I. x2 – 3(x + 5) = -11
II. y2 – 4(y + 2) = -2y
