Question
Following information has been provided by a contractor
for the year ending 31-3-2020. (a) Total expenditure till 31-3-2020 is Rs. 5,000. (b) Work certified till 31-3-2020 is Rs. 7,500. (c) Estimated further expenditure to compete the contract will be Rs. 3,000. (d) Contract Price is Rs. 11,000. Find out estimated profit of the contract.Solution
The correct answer is B
In the questions, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y and choose th...
1.3wx = 40 β wy
2. b2 = 2b + p
3. d2 + d = q
Now, observe the given conditions:
One root of equation...
I. (y β 5)2 β 9 = 0
II. x2 β 3x + 2 = 0
I. x2 β 36 = 0
II. y2 - 7y + 6 = 0
I. 2y² - 11 y + 15 = 0
II. 2x² + 3x – 14 = 0
I. x² - 33x + 270 = 0
II. y² - 41y + 414 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 11xΒ² - 93x + 88 = 0
Equation 2: 13yΒ² + 118y + 93 = 0
l). pΒ² - 29p + 204 = 0
ll).Β qΒ² + 4q - 221 = 0
Between what values of x is the expression 19x - 2x2Β - 35 positive?
I). p2 + 17p - 234 = 0
II). q2 - 21q + 108 = 0
