select the alternative which will improve the bold part of the sentence. In case no improvement is needed, select ‘no improvement’. I hope this letter finds you in good state and all were well at home.Solution
When all is used as singular noun we use singular auxiliary verbs with them; eg. All is well here. But when we use all as a plural noun we use plural auxiliary verbs with them as the above sentence.Â
I. 3x2Â + 3x - 60 = 0Â Â Â Â Â
II. 2y2Â - 7y + 5 = 0Â
Quantity I: A vessel contains a mixture of milk and water in the ratio of 7 : 5. If 9 litre of mixture is sold and replaced by same amount of water then...
I. 2x² + 15 x - 27 = 0
II. 3 y² + 25 y - 18 = 0
I. 5q = 7p + 21
II. 11q + 4p + 109 = 0
I). p2 - 20p + 51 = 0,
II). 2q2 - 7q + 6 = 0
Equation 1: x² - 250x + 15625 = 0
Equation 2: y² - 240y + 14400 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 19x² - 88x + 100 = 0
Equation 2: 17y² - 79y + 90...
I. 2p2 + 25p – 13 = 0
II. 2q2 – 19q = 2q + 23
I. 5x² - 24 x + 28 = 0  Â
II. 4y² - 8 y - 12= 0  Â
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...
