Answer:
a: £60
b: P = £36, Q = £24
Step-by-step explanation:
first find the total fraction contributed by P and Q:
3/5 + 2/3 of the remaining
3/5 = 9/15, the remainder of the fund is 6/15
so to add 2/3 of the remainder, we add 2/3 of 6 which is 4
9/15 + 4/15 = 13/15 so, in total P and Q contribute 13/15
this means that R contributes the rest which is 2/15 and we know he contributes £8, therefore 2/15 = £8 and 1/15 = £4
to find the total of the fund (15/15), we do 4 x 15 to get £60.
to find P's contribution (9/15), we do 4 x 9 to get £36.
to find Q's contribution (6/15), we do 4 x 6 to get £24.
hope this helps :)
