- Ans:3-9:6:3
given that p amount increase by 50% in 5 years
i.e. (150/100)p=p(1+R/100)^5.........(1)
we get (15/10)=(1+R/100)^5
now again its given that
x(1+R/100)^10=y(1+R/100)^15=z(1+R/100)^20
from eq (1)
=>x(15/10)^2=y(15/10)^3=z(15/10)^4
=>x=y(15/10)=z(15/10)^2
by solving above eq
x:y=3:2 and y:z=3:2
i.e x:y:z=9:6:4 - 10 years agoHelpfull: Yes(26) No(2)
