Question
If half of the umbrellas not sold in city A, then find
the difference between the numbers of umbrellas sold in city A and city E. Study the following Pie-chart carefully and answer the questions given below: The following Pie Chart shows the sales of umbrellas in 6 different cities (A, B, C, D, E and F) of North India in the month of August. Total number of Umbrellas sold in August = 4200Solution
Number of umbrellas sold in city A = 1/2 × 4200 ×  (10/100) = 210 Number of umbrellas sold in city E = 4200 ×  (14/100) = 588 Required difference = 588 – 210 = 378
I. 6x² + 37x + 45 = 0
II. 3y² - 11y + 6 = 0
I. 3y² - 20y + 25 = 0
II. 3x² - 8x + 5 = 0
if x satisfies 3x² – 5x – 12 = 0, find the sum of reciprocals of roots.
I. 96x² + 52x - 63 = 0
II. 77y² + 155y + 72 = 0
I. 2x2 - 5x - 33 =0
II. 2y2 + 5y - 25 = 0
Equation 1: x² - 180x + 8100 = 0
Equation 2: y² - 170y + 7225 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 41x² - 191x + 150 = 0
Equation 2: 43y² - 191y + ...
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...
Roots of the quadratic equation 2x2 + x – 528 = 0 is
I. 4x² -  15x + 9 = 0
II. 20y² -  23y + 6 = 0
