Sum of two numbers is 24.find numbers if product is maximum
Let one number is x and other is 24-x
X(24-x)should be maximum
24x-x^2 Derivative of this function is
Again second derivative =-2
By second derivative test it should be maximum
At x=12 so other will be also 12
It satisfied condition that the product is maximum
find x so that x+2,4x and 6x+1 are terms of an arithmetic sequence
e none of the above
if a ,b ,c are in AP than we know that b=a+c/2 or 2b=a+c
by same application
solution is option C
