Answer:
Q completes the work first
Step-by-step explanation:
P's work
for 1/4 work -10 days
for 4/4(total work) - x
by cross multiplication
x/4=10
x=4*10=40
P takes 40 days to complete the total work
Q's work
for 40% work - 15 days
for 100% work ( total work) - y
by cross multiplication
40y=1500
y=1500/40
y=37.5 days
Q takes 37.5 days to complete the total work
R's work
for 1/3 work - 13 days
for 3/3 work(total work) - z
by cross multiplication
z/3=13
z=13*3
z=39 days
R takes 39 days to complete the total work
37.5<39<40
Q<R<P
