Sir agar pehele 2b^2=9ac bata diya ho toh roots ke relation kaise nikale?
Let α and β be two roots of the equation ax²+bx+c=0 Then α + β = - b/a and αβ = c/a Now given that , 2b² = 9ac => 2b²/a² = 9ac/a², dividing by a² => 2(b/a)² = 9c/a => 2{-(α + β)}² = 9αβ => 2(α² + 2αβ + β²) = 9αβ => 2α² + 4αβ + 2β² = 9αβ => 2α² - 5αβ + 2β² = 0 => 2α² - 4αβ -αβ + 2β² = 0 => 2α(α- 2β ) -β( α - 2β) = 0 => (α- 2β )( 2α - β) = 0 => (α- 2β ) = 0 and ( 2α - β) = 0 => α = 2β and 2α = β => The relation between the roots : That one root of the equation is twice of the other root.

B✖ D✔ Explanation: Total Frequency = 78( Even ) Median = ( n/2 + ( n/2 + 1 ) ) /2 ( If Even ) = ( 78/2 + ( 78/2+1 )) /2 = ( 39 th variate + ( 39 + 1 th variate)) /2 = ( 39 th variate + 40 th variate ) /2 So, it will between 39 and 40 Option B and C Both it will Contain So, Correct Answer is D✔
Thanks for ur comment ! 1. The question is that ' median class ' not ' median '. 2. The formula u hve used is for discrete data not for continuous data ,there is no concept of even or odd in case of continuous data. so rectify ur concept here । Correct answer B✓ Thanks a lot ! @mdmozammil0916
