Question
A trader allows two successive discounts of 20% and 10%
on selling an article. If he gets 550 for that article, find its marked price.Solution
Let the MP be Rs. x ATQ: => x × 80/100 × 90/100 = 550  => x = (550 × 100 × 100)/(80 × 90) = Rs. 763.33
I. 2x² - 7x + 3 = 0
II. 8y² - 14y + 5 = 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). 5p2 Â - p - 4 = 0
II). q2 - 12q + 27 = 0
(i) 2x² – 9x + 10 = 0
(ii) 4y² – 12y + 9 = 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...
