Question

if x=50, y=40, find: x+=y--*8/x++ +y​

Answer 1

Answer:

If x = 5 and y = 4 ,

Then x = ++x + ++y will be …

x => (1+5) + (1+4)

x => 6 + 5

x => 11.

And value of y was incremented by 1 ,

So , y => 1+4

y => 5.

or

Given, x+y=10

⇒y=10−x ...(i)

Now, f(x)=xy=x(10−x)=10x−x

2

Thus f

′

(x)=10−2x

For maximum value of f(x), put f

′

(x)=0

⇒10−2x=0⇒x=5

Thus x=5 and y=5 [from equation (i)]

Hence, maximum value of xy=5×5=25.
