The total weight of peter, david and henry is 123 kg. peter is 15 kg heavier than david. david is 3 kg lighter than henry. find henry's weight.

Let me break this down with what we know like:

-David + Henry + Peter = 123kg

-Peter is 15kg heavier than David

-David is 3kg lighter than Henry

Now that we know this we can break things down.

The ratio of the 3 people is this:

- (0:3:15)=(David:Henry:Peter)

And these 3 numbers are equivalent to 18+ start with a increase of 3 every weight plus added to find all 3 of their weights, so if there is an increase of 3 and a start of 18 then we can make an equation for example:

123kg = 3x + 18

105 = 3(35)

105 = 105

So we know all 3 other than the info we knew from before which is about 11.6, So if all of them have about 11.6. So everyone's weight would be:

-David is about 11.6kg

-Henry is about 14.6kg

-Peter is about 26.6kg

Hope this helps ^^

3D=123-18.

D=35

so David(D)=35

Peter(P)= 15 + 35=50

so (P)=50

and henry(H)=D+3= 35+3=38

Henry(H)= 38

10
