Hello, everyone in this question.
00:02
We have to find out any 2 posterial number, so there with product is maximum and sum is given 110 point.
00:10
So what they'll do numbers are? 1 number is x.
00:18
Another number is y, so, according to given term what i can write x, plus y, equals to 110 point now from here y equal to i can write 110 minus x.
00:29
That's say this is question number 1 point now.
00:31
If we talk about products of products of these 2 numbers, what i can write x into y now y ai from equation 25 foot here when i get into 110 minus x, so if i simplify, then i'll get 110 x minus x square.
00:48
So, finally, if i write, then i'm getting minus x square plus 110 x now this product- this is a female product, so this product will be maximum when x will be minus b by 2, a formula is minus, b by 2, a so minus b by 2.
01:07
A if i find so minus into value is 110 side by 2 into a value.
01:14
Is minus 1 point? so if i simplify that 110 divided by 2, this is equal to 55 point...
