00:00A plus 3 divided by C plus 1 equals C plus 3 divided by B plus 1, which equals B plus
00:03The ratio given is 3 divided by A plus 1, which equals 7.
00:06According to this, we are asked for the sum of A plus B plus C.
00:09What do I mean by A plus 1 plus C, friends?
00:14Let's say it's X.
00:16Now, friends, when we look at this in terms of our proportion, what were we doing?
00:20When we add up their numerators and denominators and then ratio them, the overall ratio will not be equal to six, which is 7.
00:27Really?
00:27Yes.
00:27Then this is what I do.
00:28A plus 3 plus C plus 3 plus B plus 3 divided by C plus 1 plus B plus 1 plus
00:37A plus 1 equals 7, according to our proportion.
00:43So what did we say?
00:44We said let's have B plus C plus X.
00:46X plus this plus C plus B, and we also have the sum of 3 6 9, folks.
00:52Wouldn't we find X plus 9 divided by C B A as X plus 3, which equals 7?
01:00When we solve this equation and find X, we will now have found it in the sum of B plus C plus X.
01:04Okay, so when I do the multiplication, friends, 7 times X plus 21 equals X plus 9.
01:12What happens if we move X to this side and 21 to that side?
01:166 times X equals X plus 12. Our X is less than B plus C, so our total is X plus 12.
01:27We find our answer to be incomplete.
