Question
Find the total profit in the year 2014, if the
investment of Panna is half of the investment of Moti in the same year and the profit of the Heera is 22000 ? Study the following table carefully and answer the questions that follow . Three persons Heera, Moti and Panna invested different amounts in different years for different years for different time periods and shared profit from the total profit given as per table. Some values are missing. Answer the questions on the basis of given table and information in question.Solution
I. x² + 11x + 24 = 0
II. y² + 17y + 72 = 0
(i) x² – 3x – 40 = 0
(ii) y² + 11y + 30 = 0
I. 4x2 + 25x + 36 =0
II. 2y2 + 5y + 3 = 0
l. p2Â - 3p - 54 = 0
II. q2Â - 19q + 90 = 0
Solve: x² − 7x + 12 = 0
(i) 2x² – x – 3 = 0
(ii) 2y² – 6y + 4 = 0
The nth term of a sequence is n² + 3n + 1. Find the difference between the 20th and 10th terms.
I. 2y2Â + 31y + 99 = 0
II. 4x2 + 8x – 45 = 0
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer Â
I. 7x² - 19x + 10 = 0...
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 32x + 207 = 0
Equation 2: y² - 51y + 648 = 0
