Let the total capacity of the tank be .
When it's full it can contain 450 liters.
Now lets find its total capacity. If then
So when it's full, there will be liters.
Hey i was looking for help on these problems; how would i go about finding the solutions to them both?
1.If a storage tank is holding 450 liters when it is three quarters full, how much will it contain when it is two thirds full?.
And
2.three people P,Q and R contribute to a fund. P provides 3/5 of the total, Q provides 2/3 of the remainder and R provides £8. determine a) the total of the fund. b)the contributions of P and Q.

P provies of total which is , now the remaining is .
Q provides of the remainder, so that is the amount Q gives.
R gives 8£, it's equal to .
( )
I substracted the amount Q provided ( ) from the total fund left ( ) after P's contribution.
So we know that 8£ of the total amount. 60£ is the total amount.
From here we can find P's contribution which is 36£ and Q's, 16£
