Question
Find the ratio of the total males in Delhi and
Chandigarh together to the total number of females in the same cities together.Solution
Number of bank aspirants in Delhi = 11% of 24500 = 2695 Number of males = 40% of 2695= 1078 Number of females = 2695 – 1078= 1617 Number of bank aspirants in Chandigarh = 24500 × 21/100 = 5145 Number of males = 5145 × 1/5= 1029 Number of females = 5145 – 1029 = 4116 Therefore, Required ratio = (1078 + 1029) : (1617 + 4116) = 2107 : 5733 = 43 : 117
I. x2 - 11x + 24 = 0
II. y² - 5y + 6 = 0
